A Cepheid is No More: Hubble's Variable 19 in M33
TL;DR: In this paper, the authors report on the remarkable evolution in the light curve of a variable star discovered by Hubble (1926) in M33 and classified by him as a Cepheid.

TL;DR: In this article, the authors quantify the sensitivity of the stellar brightness of the GJ 581 system to shallow transit signals using Monte Carlo simulations, and perform a transit search within the 3$σ$ transit windows corresponding to both the circular and Keplerian orbit ephemerides.

TL;DR: The contribution of the HATNet project to extrasolar planet science is summarized in this article, highlighting published planets (HAT-P-1b through HAT-26b) and summarizing what HAT provides to the exoplanet community with each discovery.

TL;DR: A considerable variability in isotopic compositions and water contents among various planetary materials in the inner Solar System (Fig. 1) is now well established as mentioned in this paper, which means that mixing of bulk of the material during accretion, at least in some regions of the inner solar system, was limited.

Predictions of the atmospheric composition of GJ 1132b
TL;DR: In this article, the interaction of a magma ocean with a water-rich atmosphere on GJ 1132b was studied and it was determined that it must have begun with more than 5 wt% initial water in order to still retain a waterbased atmosphere.
