Sirius A, the brightest star in the night sky, has a radius approximately 1.71 times that of the Sun. To calculate its surface area, you can use the formula for the surface area of a sphere: (4\pi r^2). Using its radius, the surface area of Sirius A is roughly (3.68 \times 10^{13}) square kilometers.

What is Sirius Surface temperature?
The surface temperature of Sirius A, the primary star in the Sirius binary system, is estimated to be around 9,940°C (17,984°F). Sirius B, its white dwarf companion, is much hotter with a surface temperature of about 25,000°C (45,000°F).
How hot is Sirius?
Sirius is a binary star system with two main stars, Sirius A and Sirius B. Sirius A, the brighter and more massive star, has a surface temperature of around 9,940°C (17,964°F). Sirius B, the smaller and fainter star, has a surface temperature of about 25,200°C (45,332°F).
What is the celsius temperature of Sirius?
Sirius is a binary star. The temperature of Sirius A is roughly 10,000 degrees and Sirius B is about 25,200 degrees. These are only rough estimates as it is extremely hard to measure the exact temperature of something so hot

When is the sirius B star going to burn out?
It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.

What can you infer about Sirius's size and temperature that would explain why it look's brighter than Barnard's Star?

What star has a surface temperature 9000k and luminosity about 1 to 20 times greater than the sun?
Sirius
What star is brighter than Sirius?
Observed from Earth there are no brighter stars at the night sky. If you see something that is brighter, it will be a planet.
Is aldebaran hotter brighter or both than Sirius?
Aldebaran is both hotter and brighter than Sirius. Aldebaran, a K-type giant star, has a surface temperature of about 4,000 K and a luminosity approximately 440 times that of the Sun. In contrast, Sirius, an A-type main-sequence star, has a surface temperature of around 9,900 K but is less luminous than Aldebaran, at about 25 times the Sun's luminosity. Therefore, while Sirius is hotter, Aldebaran outshines it in brightness.
