In today’s astrobite, we take a fresh new look at an old problem: modeling the envelopes of CO gas around evolved stars.
There are nearly 10,000 galaxies in this image, with a staggering variety of shapes, colors, sizes, and ages. But buried beneath that variety, we can find patterns in how galaxies morph and evolve over time. Today’s astrobite explores one such set of links in the giant chains of galaxy evolution.
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
Techniques in astrostatistics help astronomers characterize large amounts of data. The authors of today’s astrobite use data-driven astrostatistics to distinguish between populations of hot Jupiters in a sample. It’s a technique that can definitely be put to good use over the next few decades, as oodles of observations pour in from the new telescopes of the 21st century.
Characterizing planets through direct imaging is no easy task! But today’s authors offer a work-around formula, which estimates the crucial parameter of planetary mass from protoplanetary disk observations. In this astrobite, we discuss ‘The Theory’ and ‘The Practice’ of their cool equation.
