This month’s undergraduate research post features an analysis of distance-indicating RR Lyrae stars, and transiting exoplanet science using a code called OSCAAR.
The Kepler Space Telescope gets a promising second chance with a new mission called “K2″.
How do so many hot jupiters come to orbit backwards?
We are used to thinking about planet transits in visible wavelengths. What can we learn from planet transits in the radio band? Today, we discuss what these transits might tell us about the magnetic activity and the atmosphere of a star.
NASA is looking for a new mission for the damaged Kepler space telescope. Here are some ideas.
Highlights from the International Astronomical Union Symposium on “Exploring the Formation and Evolution of Planetary Systems”.
Our simple formula for predicting the probability that an exoplanet will transit might miss something important.
Faigler et al. apply their BEER algorithm to a collection of stars in the Kepler field and find a hot Jupiter missed by the Kepler Science Team, showing a new way to find and characterize planets without follow-up observations.
The census of planets for smaller stars—M dwarfs—is now basically complete. In this paper, Courtney Dressing and Dave Charbonneau use this M dwarf advantage to determine the occurrence rate of small planets around M dwarfs.
By looking for variations in the observed periods for eclipsing binary stars, astronomers have found evidence that a sizable fraction of these systems are actually systems of three or more stars.
