Is this a white dwaf?
Posted: Posted January 28th
Edited January 28th by Louis De Pointe du Lac

Sirius is the brightest star in the night sky. It also has a white dwarf companion known as Sirius B. It is about 10,000 times less luminous than Sirius A - the main star.

On Thursday night I stacked an image of Sirius and found a bulge next to it.



I don't know whether this is the faint light of the white dwarf or just left over atmosphere distortion or maybe a stacking error. So I trained my telescope on Sirius again last night and got a better image. I also used some gamma editing to highlight weak sources of light.



Now it is actually possible to see Sirius B with a telescope as shown below, but I'm still skeptical. I'm gonna clean the lens and focus on a few more objects tonight. If I still see the same extra light source from Sirius and not on other objects, then that builds a good case for the white dwarf possibility.
