Could Companion Stars Cause Stripped-Envelope Supernovae?
How do you make a supernova without hydrogen and helium lines? The answer may surprise you! (It’s probably binary stars)
The Secret of T Pyx
T Pyx is a mystery. The stellar systems appears to contain a white dwarf and companion star. However, the white dwarf is accreting mass from its companion way faster and way more efficiently than it should, resulting in novae eruptions every 30 years.
Today’s authors may have found the culprit for these frequent explosive hydrogen burnings, which should not be possible in theory.

What we still don’t know about accretion disks
Today’s dual-language post takes a look at a classic paper of Shakura & Sunyaev written in 1973. Whilst this paper advanced our understanding of accretion disks, we still have an incomplete theoretical picture. That may all change
