A Red Giant With A Flare

Red giant stars are huge red giant

Red giant stars are huge. Luminous stars with small or intermediate masses of approx. 0.3 to 8 times bigger than our own interplanetary. The Sun. These older giant stars are in the last stages of stellar evolution and are on their way to facing their inevitable doom. Orange-yellow to red in color, a red giant’s outer atmosphere is both high and weak. Giving a huge radius with a very low surface temperature of 5,000 Kelvin, or less.info technology hub

In May 2015, extremely sharp observations by a team of astronomers using the Atacama Large Millimeter / Submillimeter Array (Alma) reveal what appears to be a giant flare on the external of Mira. One of the maximum celebrat and contiguous Red Giant leads. of the world. Heaven from earth. However An activity like this on a red giant star comes as a surprise to astronomers and can help explain how the winds that collide with giant stars make a valuable contribution to our Milky Way ecosystem.

Alma is an astronomical red giant

Alma is an astronomical radio telescope interferometer  red giant located in the Atacama desert in northern Chile. The new observations made with Alma have given astronomers their best view of the well-known double star Mira yet. The sharp images reveal the duo with stars that make up the binary system called Mira A and Mira B.  red giant But that’s not all! For the first time at millimeter wavelengths, the new images reveal previously hidden details on the surface of Mira.

Red giant Alma’s apparition is so high-pitch that we can inaugurate to see minutiae on the exterior of the star. Part of the surface of the star is not only extremely bright But it also varies in brightness. It red giant must be a huge glare, and we think it’s related. with a flare that X-ray telescopes observed a few years ago Explained Dr. Wouter Vlemmings in a press release from Chalmers University of Technology in May 2015. Dr. Vlemmings is an astronomer at Chalmers and led the team. Chalmers University of Technology is in Gothenburg, Sweden red giant .

The team’s study was published red giant

The red giant team’s study was published in the May 13, 2015 issue of the journal Astronomy & Astrophysics.Look. Which in Latin means “Wonderful”.Has been known for hundreds of years and is one of the most famous variable stars in the sky. At its brightest, it can be seen clearly with the human eye unaided, but when it is at its weakest, a telescope is absolutely necessary. The star is 420 light-years distant in the constellation Cetus, and consists of a duo of stars of roughly the same mass as our sun: one is a cold. Puffy red giant and the other is a small, dense type of star. and warm. called white dwarf. The two stars orbit each other at a distance equal to the average distance of the dwarf planet Pluto from our sun.

 

Red giant stars and the fate of our sun red giant

 

Most red giants are stars approaching the end of the long stellar path. But they have some. Left because they still melt hydrogen into helium in a shell surrounding a degenerate helium core. The closest red giant star to Earth is Gamma Crucis, which is 88 light years away. However, an orange giant star. Arcturus is consider by some astronomers to be a red giant, 36 light-years distant.The  Giants are older stars that have ingest the necessary supply of hydrogen in their cores and have begun to melt hydrogen in a shell surrounding the core.

They have impressive radii that are ten to hundreds of times larger than our suns. However, their outer shell has a much lower temperature, which is why they have a cool orange-red color. Many times brighter than our sun, the envelopes of the Red Giants have lower energy density due to their enormous size. In fact. The Red Giants have glows that are approximately one hundred to several hundred times larger than our own star.
