The component A of this system is a G2V star (see Spectral Type) with a mass of 1.1 solar-masses, a luminosity of 1.519 times solar, and an effective temperature of 5,790 K. Its component B has a spectral type of K1V and its mass, luminosity, and effective temperature are equal ...
‘tail’). Deneb is one of the biggest and brightest stars known, with a mass at least 25 times that of the Sun. It has a luminosity of between 60 000 and 250 000 times the Sun's brightness, depending on the accuracy of our distance estimates for it. It has very low proper motion...
Proxima Centauri Luminosity Luminosityis the amount of energy a star pumps out relative to the amount that our star, the Sun, gives out. Our star, the Sun's value is 1. Proxima Centauri luminosity figure of 0 is based on the value in the Simbad Hipparcos Extended Catalogue at the Universi...
Compute many different astrophysical concepts from stellar luminosity to cosmology. Kepler's third law, 4 solar masses, 5 Earth masses, 2.5 AU Compute cosmological properties of the universe: 1 billion years after the big bang More examples ...
The temperature profiles are given by the following: 𝑇A(𝑅)=690(𝑅/1au)−0.5TA(R)=690R/1au−0.5 K and 𝑇B(𝑅)=581(𝑅/1au)−0.5TB(R)=581R/1au−0.5 K, thereby considering that stars A and B do not have the same mass and luminosity. 2.3. Circumstellar Discs ...
Alpha Centauri is the closest star system to Earth and is made up of three stars and several exoplanets. We explore our stellar neighbors in more detail here.
ALPHA CENTAURI Ais close to our sun in age and luminosity. Alpha Centauri A and B orbit closely to each other. ALPHA CENTAURI Bis smaller and dimmer than our sun. But it’s still not too different from our sun. ALPHA CENTAURI C (PROXIMA CENTAURI)is a smaller red dwarf star with a muc...
Alpha Centauri is the third brightest star in the night sky. To the naked eye it shines atapparent magnitude-0.27, which is fainter thanCanopus (mag. -0.72)but brighter thanArcturus (mag. -0.04). However, Alpha Centauri is not a single star; it's a triple consisting of two bright compo...
