- Betelgeuse. Betelgeuse is the tenth brightest star in the sky. It is a red supergiant about 13,000 times brighter than our sun and over 1000 times larger. If you placed Betelgeuse in the place of our sun, it would extend past the orbit of Jupiter.

- Type Ia supernovas, in contrast, are observed in all kinds of galaxies, and are produced by white dwarf stars, the condensed remnant of what used to be sun-like stars. A white dwarf star, a dense ball primarily composed of carbon and oxygen atoms, is intrinsically the most stable of stars, as long as its mass remains below the so-called Chandrasekhar limit of 1.4 solar masses.

This Weekâs Sky at a Glance, September 11 â 19 Monday, September 14. • Altair is the brightest star in the south after dark. Look for Gamma Aquilae (Tarazed) to its upper right by a finger-width at arm's length, and fainter Beta Aquilae a little farther on the opposite side of Altair. Delphinus, the Dolphin, is about a fist-width to Altair's left.

What kind of stars are cool and bright? To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright. To be bright you need to be hot, close or have a large surface area.

KenCroswell.com This makes the star about one third as old as the Sun. Procyon is the brightest star in Canis Minor and the eighth brightest star in the night. It's a yellow-white F-type star evolving from the main sequence to the subgiant stage. Someday it will become a red giant. In the 1990s, astronomers detected tiny oscillations on Procyon.

The 10 Brightest Stars in the Sky Sirius, also known as the Dog Star, is the brightest star in the night sky. Its name comes from the Greek word for scorching. It's actually a double star system, with a very bright primary and a dimmer secondary star. Distance: 8.6 light-years.

Very bright star in the east at northern hemisphere. What is it? Sirius - the brightest star in the sky. I've seen it myself - and on a good, dark night, it can really stand out. Jupiter - the king of the planets is also rising at about the same time. It is brighter than any star in the sky, by a wide margin (though fainter than Venus), and it can really stand out.

Procyon 2 Alpha Canis Minoris A, the Little Dog Star, is the eighth brightest star in the night sky as well as the brightest star in its constellation. Unlike Sol, it is a white-yellow main sequence dwarf star of spectral and luminosity type F5 IV-V (Mosser et al, 2008).

- A red dwarf is a small and relatively cool star on the main sequence, of either K or M spectral type. Red dwarfs range in mass from a low of 0.075 to about 0.50 solar mass and have a surface temperature of less than 4,000 K.

Lecture 13 Main Sequence blue giants such as Rigel are located on the left-hand side of the H-R diagram. The order is O B A F G K M, and these are spectral classes based on color and tem … perature. The hottest stars burn blue/white because blue light has the shortest wavelengths and the highest temperatures.

Universe Today Space and astronomy news Dwarf Star. A dwarf star is a star that is not a giant or supergiant … in other words, a dwarf star is a normal star! Of course, some dwarf stars are much smaller (less massive, have a smaller radius, etc) than normal (or main sequence, not really massive) stars … and these have names, like white dwarf, red dwarf, brown dwarf, and black dwarf. Our very own Sol (the Sun) is a dwarf star … a yellow dwarf.

Stars The smallest stars, known as red dwarfs, may contain as little as 10% the mass of the Sun and emit only 0.01% as much energy, glowing feebly at temperatures between 3000-4000K. Despite their diminutive nature, red dwarfs are by far the most numerous stars in the Universe and have lifespans of tens of billions of years.

- The temperature of an object determines the type of radiation it emits. Hence, every star radiates energy with wavelengths corresponding to its surface temperature: a cooler star would radiate a more reddish light, a hotter one a more bluish one. Reddish and bluish stars can be seen readily in the night sky.

- View full size image. Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky. The name means glowing in Greek. With a visual magnitude of -1.46, the star is outshone only by several planets as well as the International Space Station. Because Sirius is so bright, it was well-known to the ancients. What came as a surprise to astronomers was the discovery of a companion star, Sirius B, in 1862.

Sirius Sirius (/ˈsɪri.əs/, a romanization of Greek σείριος, Seirios, lit. glowing or scorching) is a star system and the brightest star in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star.

Stars A star's brightness is known as its magnitude. Astronomers rate the magnitude of a star with a scale that gives brighter stars a low number and dim stars a higher number. Each whole number on this scale is 2.5 times dimmer than the previous number. The brightest star the night sky is Sirius.

Yellow Dwarf Yellow Dwarf. A yellow dwarf is a star and is often referred to as a G-type main sequence star. A perfect example of a yellow dwarf would be the sun. A yellow dwarf has a mass almost like the mass of the sun. Its color ranges from white to a lighter yellow.Among the stars in the galaxy, yellow dwarf stars are bigger than most of the stars although giant stars are the biggest of all. perfect example of a yellow dwarf would be the sun. A yellow dwarf has a mass almost like the mass of the sun. Its color ranges from white to a lighter yellow.

How many different types of stars are there? If a star has between 1.35 and 2.1 times the mass of the Sun, it doesn’t form a white dwarf when it dies. Instead, the star dies in a catastrophic supernova explosion, and the remaining core becomes a neutron star. As its name implies, a neutron star is an exotic type of star that is composed entirely of neutrons.

dwarf star Other kinds of dwarf stars result from the further evolution of main-sequence stars not massive enough to become neutron stars or black holes (which form from the burned-out core of a supernova). The type known as a white dwarf is the remnant of a red giant star that has burned nearly all its fuel.
