TL;DR: Observations reveal the presence of a small planet with a minimum mass of about 1.3 Earth masses orbiting Proxima with a period of approximately 11.2 days at a semi-major-axis distance of around 0.05 astronomical units.

TL;DR: In this article, a low-amplitude periodic signal with a period of 233 days was found to arise from a super-Earth around Barnard's star, with a minimum mass of 3.2 times that of Earth orbiting near its snow line.
Journal ArticleDOI
Fast radio bursts: the observational case for a Galactic origin
Dan Maoz,Abraham Loeb,Abraham Loeb,Yossi Shvartzvald,Yossi Shvartzvald,Monika Sitek,Michael Engel,Flavien Kiefer,Marcin Kiraga,Amir Levi,Tsevi Mazeh,Michał Pawlak,R. Michael Rich,Lev Tal-Or,Lukasz Wyrzykowski +14 more
TL;DR: In this article, the authors used time-domain optical photometry and spectroscopy to find possible flare stars in additional fast radio bursts (FRB) fields, with one to three such cases among eight FRB fields studied.
Journal ArticleDOI
The Color-Magnitude Diagram in Baade's Window Revisited
TL;DR: In this paper, the authors reanalyzed the OGLE V and I photometry of ~500,000 stars in Baade's Window, and confirmed the extinction map published by Stanek.
Journal ArticleDOI
