The key to understanding how these worlds are built is to consider where they are missing.
The Milky Way’s nearest neighbor, the Andromeda galaxy, is a promising target for deep multi-wavelength observations. Come listen to Prof. Julianne Dalcanton talk about her work catching up with the neighbor at #AAS233!
Why is our Sun so anomalously stable in brightness compared to other stars? The authors of today’s paper decided to run some simulations to find out.
There are a lot of Sun-like stars in the universe. Are they as identical as the name suggests, or are there important differences between them?
I attempt to summarize what some astronomers have called “undoubtedly the most brilliant Ph.D. thesis ever written in astronomy.”
Measuring a white dwarf’s gravitational redshift can help us figure out its mass, but for one of the closest stars to us (Sirius B) the numbers didn’t match with other methods. Today’s paper investigates the discrepancy.
