The red-giant branch variable star Gamma Crucis is the nearest M-class giant star at 88 light-years. [25] The K1.5 red-giant branch star Arcturus is 36 light-years away. [ 26 ]
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [102]
This red giant star will, one day, explode as a supernova. ... We found the second smaller event was likely due to the pulsations of the star,” Dr. Meridith ... This new study finds its body ...
A variable star of a different kind is Tau 4 Serpentis, a cool red giant that pulsates between magnitudes 5.89 and 7.07 in 87 days. [40] This star has been found to display an inverse P Cygni profile, [41] where cold infalling gas on to the star creates redshifted hydrogen absorption lines next to the normal emission lines. [42]
The red giant π1 Gruis is 530 light-years away, and it's reaching the end of its natural life. Soon, scientists think it will become a planetary nebula. But before it dies, astronomers are using ...
Stars that are at least sometimes visible to the unaided eye have their apparent magnitude (6.5 or brighter) highlighted in blue. The first list gives stars that are estimated to be 60 M ☉ or larger; the majority of which are shown. The second list includes some notable stars which are below 60 M ☉ for the purpose of comparison. The method ...
Infrared images show a red giant star, located 30,000 light years away near the center of the Milky Way. The star faded away and then reappeared over the course of several years. - Philip Lucas ...
The red clump should not be confused with the "red bump" or red-giant-branch bump, which is a less noticeable clustering of giants partway along the red-giant branch, caused as stars ascending the red-giant branch temporarily decrease in luminosity because of internal convection. [10]
