Newly EAO-discovered stars named after Sheikh Zayed

ABU DHABI, 14th December 2021 (WAM) – The Emirates Astronomical Observatory announced today the discovery of a number of new Variable stars in conjunction with the World Space Week, which concluded today, where the head of the team of the Emirates Astronomical Observatory Engineer Nezar Sallam was able to discover 3 Variable Stars and record and adopt this discovery in the record of the 'The International Variable Star Index' .

Sallam said: ''The new discovery has been officially registered and recognized at the American Association of Variable Star Observers (AAVSO) and the adoption of the star name in the International Variable Star Index.''

He continued, "In this way, the Emirates Astronomical Observatory has recorded a new scientific achievement in addition to the discovery announced late last year, which was represented by its co-discovery of two new planets that were formed about a billion years ago outside the boundaries of the solar system."

Sallam added: ''The variable stars, symbolized by the letter V, are a category of stars whose apparent brightness changes in a persistent or variable pattern with respect to an observer on the surface of the Earth, so that the star moves from a certain degree of brightness to a degree of greater or less powerful brightness for various reasons. Different and it is one of the stages in which the star lives, where there is a change in the degree of brightness or in the stellar mass.''

The importance of searching for variable stars lies in providing information about stellar properties of stars, such as mass, radius, internal and external structure of stars, composition, and stages of development, in addition to providing information about luminosity, temperatures, and by discovering and studying them, we can measure the distance between us and other galaxies. .

Some of the Star discovery was made directly through the observatory equipment, as is the case with the star Zayed-V1 and through the use of data provided by the Transiting Exoplanet Survey Satellite (TESS) and All Sky Automated Survey for SuperNovae (ASAS-SN) survey satellites. These stars were monitored by the Emirates Astronomical Observatory and their data was analyzed using software and mathematical algorithms, drawing their light curves in order to submit discovery reports, approval and registration after naming it.

The head of the observatory revealed that (Zayed Star V1), and the new name adopted in the catalog of variable stars index is (Zayed-V1), is located in the constellation called (Vulpecula), and it is of the type of variable stars EW, which are stellar eclipses that occur with periods shorter than one day, which causes a discrepancy In the apparent brightness of a star and in the case of Zayed V1, the period about 8 hours and occurs 3 times over a day. The Mag. range between 18.46-18.92 by the Sloan r filter.

The Variable Star (Zayed-V2), located in the stellar group called (Perseus). They are stars that rotate and pass in front of each other, causing a change in their luminosity and a blocking of their light emanating from them, as seen by an observer from the surface of the Earth. The Mag. range 11.78 to 11.84 (in Johnson V optical filter measurements) and is of the EA variable star and the spectral type A5V star. A period about 3.8 days and lasts about 4.6 hours.

The variable star (Zayed-V3) was discovered in the constellation called (Camelopardalis), it is of the type of DSCT, the spectral type of the star is A0, and the Mag. range is 8.27 V (Johnson V) by TESS .and shows variations in its brightness period 64.92 minutes.

Sallam explained that the stars were photographed using an Astronomical Observatory with a diameter of 0.6 meters, using a specialized astronomical camera at a cooling temperature of minus 30 degrees Celsius, an optical filter (Johnson V) and an optical filter (Sloan r) to provide accurate optical readings of the observed stars in order to be able to complete The process of discovery, registration and official recognition.

Dubai Police warns Against Using Police Emergency Strobe Lights

The Dubai Traffic Police has recently warned motorists against using police and emergency vehicle warning lights, after two vehicles were spotted on the road taking advantage of the exclusive entitlement of the police to be given way in case of emergency.

Colonel Juma bin Suwaidan, Acting Director of the General Traffic Department, urged road users to adhere to traffic laws to avoid facing legal liabilities and prevent endangering their lives and others.

Col bin Suwaidan stated further that the police patrols had impounded two vehicles on two separate occasions for illegally fitting their vehicles with using emergency warning lights similar to the police, giving other motorists a false impression of authority to give way.

“We have spotted one at the Emirates Road and the other at Sheikh Mohammed Bin Zayed Road. Reports were filed against the two, and their vehicles were confiscated and fined,” he added.

Her Highness Sheikha Dr. Shamma bint Mohammed bin Khalid Al Nahyan announces the launch of the “Emirati Miniatures initiative” from the Courtauld Gallery in London.

“Art is the mirror of history and a true reflection of the extent of the civilised development of society.”

I feel a special state of spiritual and intellectual transcendence. ” Her Highness Sheikha Dr. Shamma expressed her conviction in the value of the arts and their being a title for advanced people and civilizations. This statement came during Her Highness’ visit to the Gallery in the British capital, London, at the beginning of her meetings and her visit as part of Her Highness’s cultural and knowledge programme for knowledge and human communication.

The Courtauld Gallery is interested in the history of the arts through different ages and human civilizations, and many of the senior art historians in the British scientific community belong to it. The Museum: Edouard Manet, Vanessa Bell, and Lucas Cranach (Painting of Adam and Eve), as well as the French artist Pierre Auguste Renoir, the Dutch artist Van Gogh, and many other artists.

Her Highness and the accompanying delegation were welcomed by Professor Deborah Salo, Director of the College; Dr. Karen Sears; Mrs. Francesca Hoyt and Mrs. Camilla Knight, where Her Highness and the accompanying delegation accompanied Professor Debrois on a tour between the various pavilions of the museum and the exhibition.

Her Highness held a meeting with the director of the gallery and the work team, where she thanked and appreciated them for their good reception. During the meeting, ways of cooperation between Sheikh Mohammed bin Khalid Al Nahyan’s cultural and educational institutions and between the Courtauld institutes were discussed, and experiences were exchanged in the field of presenting. There were lectures and technical workshops between the Emirati technical cadres and the technical cadres of the college, and Her Highness announced during the meeting the launching of the (Emirati Miniatures) initiative, which will be launched next October. It is an initiative dedicated to Emirati artists, using palm fronds as a basis for drawing accurate artistic miniatures that express the Emirati and human heritage. Her Highness invited them to attend the exhibition of the artworks participating in the initiative. Professor Deborah was very impressed with the idea of the initiative, especially the use of date palms, as they represent a heritage value in desert communities.

At the end of the meeting, Her Highness gifted the college a set of publications that talk about art in the United Arab Emirates, as part of the (Knowledge for Humanity) initiative launched by Her Highness last year, which aims to make the world know the Emirati civilization and its ancient folk heritage by donating museums and universities. To be among its holdings, with knowledge sources of books and technological means that define the UAE between the past, present, and future.
