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.
Based on colour alone, can we distinguish between a rocky, icy and gaseous planet?
Today’s paper explores different possibilities causing the brown dwarf CWW 89Ab to be overly bright.
Could Gaia’s immense catalog of stellar positions help us find extraterrestrial intelligence?
The redshifts of active galactic nuclei (AGNs) can help us piece together the universe’s evolutionary timeline. Unfortunately, measuring these redshifts can be pretty tricky. In today’s astrobite, we look at a trick for estimating and constraining the redshifts of AGNs that are – ironically enough – partially obscured from our view.
The annual meeting of the Astronomical Society of Australia happened last week; here’s a short summary of some of the incredible science happening Down Under!
