Beteluse: VLT Observing Darkening Supergiant Star, Astronomers using two devices in ESO’s Very Large Telescope (VLT) have captured new images of a red supergiant star called Beteluse.

Astronomers using two devices in ESO’s Very Large Telescope (VLT) have captured new images of a red supergiant star called Beteluse. The images not only show the exaggeration of faded red, but also how its apparent shape is changing.

This comparative image shows Betelgeuse, also known as Alpha Orionis, before and after its unprecedented attenuation. The observations taken with the SPHERE instrument at ESO’s Very Large Telescope in January and December 2019 show how much the star has faded and its apparent shape has changed.

Beteluse, the second brightest star in the constellation Orion, is a red supergiant, located about 650 light years from Earth. With a radius approximately 1,400 times larger than the Sun, Bethelgeus is one of the largest known stars. It is one of the brightest stars, emitting more than 100,000 suns.

With only 8 million years, Bethelues is already reaching the end of his life and is soon doomed to explode as a supernova. When this happens, supernovae can be easily seen from Earth, even in broad daylight.

Betelgeuse began to decline in September 2019. At the time of writing, the supergiant star represents approximately 36% of its normal brightness, a noticeable change even to the naked eye.

This image obtained with the VISIR instrument in ESO’s Very Large Telescope shows the infrared light emitted by the dust around Betelgeuse in December 2019. In this dramatic image, dust clouds surrounded by flames form when the star pours its contents.

Back to space The black disk greatly obscures the center of the star and the surrounding atmosphere, which are very bright and must be masked to allow smoke smoke to be seen. The orange dot in the middle is the SPHERE image of the surface of Betelgeuse, whose size is close to the orbit of Jupiter.

KU Leven astronomer Miguel Montargues and his colleagues have been watching the star with VLT since December 2019, with the aim of understanding why it is weak.

Among the first observations that came out of his campaign, there is a dazzling new image of the Bethelues surface, taken at the end of last year with the Spectro-Polarimetric high contrast exoplanet research instrument (SPHERE).

Dr. The Montarges team did the same with SPHERE in January 2019 to inspect the stars, before we started to get dark before and after the portrait of Betalges.

Taken in visible light, the images highlight changes in both brightness and apparent size. Many astronomer enthusiasts were surprised if Bettingues’s attenuation meant it exploded.

“Montargate said:” The two scenarios we are working on are surface cooling for us due to exceptional stellar activity or dust rejection. Of course, our knowledge of the Red Supergiant is incomplete and is still in progress, so a surprise may still occur.

This artist’s impression shows Bethelges as revealed in ESO’s Very Large Telescope due to several cutting-edge techniques that allowed two independent teams of astronomers to obtain the sharpest views of the supergiant star. They show that the star has a huge gas vane in the form of our solar system and a huge bubble is boiling on its surface.

These discoveries provide important clues to help explain how these giant materials shed material at such tremendous speed. Betelgeuse radio units have been provided, as well as scales compared to the solar system.

They show that the star has a gas stack almost as large as our solar system and a huge bubble is boiling on its surface.

Another new image, obtained with the VISR instrument in VLT, shows the infrared light emitted by the dust around Betelgeuse in December 2019.

Astronomer Pierre Carewella and his colleagues at the Paris Observatory made observations. The wavelength of the image is similar to that detected by heat chambers, astronomers said.
