The paper "M dwarfs: planet formation and long term evolution" describes blue dwarf stars, a hypothetical next-stage in the lifespan of red dwarf stars within a certain mass range, after …

Aug 10, 2014 · From what I've read, white stars are hotter than red ones. But a white dwarf would have just heavy elements to fuse, so shouldn't it be less bright?

Aug 11, 2020 · I read recently that a red dwarf star might actually look white. I realize there's a wide range in red dwarf surface temperature, 2,500 to 3,500 degrees K, compared to 5,778 for …

Dec 1, 2020 · The amount of blue light we see in the sky then depends on the intrinsic spectrum of the Sun and the angle between the sightline and the Sun. M-dwarfs and especially brown …

Nov 4, 2022 · One day, while researching on blue dwarfs in Wikipedia, I stumbled across something that I cannot understand: Rather than expanding, however, red dwarfs with less …

Apr 29, 2014 · Compare the effective temperature of the stars with Planck's law, and with a light bulb (2000 to 3300 K): The color of a light bulb corresponds to spectral class L (red brown …

Dec 16, 2022 · On the other hand, an orange K0 dwarf, such as Sigma Draconis, is hotter than an M class giant like Betelgeuse. Betelgeuse has an effective temperature of about 3500K. So …

Nov 21, 2018 · 1 Purple and green star exists. For example, a blue supergiant star can have its surface temperature to 50000 K, which peaks at purple in the blackbody spectrum. However, …

Aug 14, 2020 · This star is called a "blue dwarf". The star becomes cooler and less luminous. Shell burning continues during this time, eventually ending with the star having a hydrogen …

Nov 21, 2019 · Although I realise this will vary depending on e.g. mass of the star, is anything known about the length of time a B-subdwarf will remain in the subdwarf state before finally …
