TL;DR: The Coordinated Synoptic Investigation of NGC 2264 (CSI 2264) as discussed by the authors was a 30-day multi-wavelength photometric monitoring campaign on more than 1000 young star members using 16 telescopes.

TL;DR: The Next Generation Transit Survey (NGTS) as discussed by the authors is a ground-based project searching for transiting exoplanets orbiting bright stars, which is designed to achieve higher photometric precision and hence find smaller planets than have previously been detected from the ground.
Journal ArticleDOI
Magnetospheric Structure and Atmospheric Joule Heating of Habitable Planets Orbiting M-dwarf Stars
Ofer Cohen,Jeremy J. Drake,Alex Glocer,Cecilia Garraffo,Katja Poppenhaeger,Jared Bell,Aaron J. Ridley,Tamas I. Gombosi +7 more
TL;DR: In this article, the magnetospheric structure and the ionospheric Joule Heating of planets orbiting M-dwarf stars in the habitable zone were studied using a set of magnetohydrodynamic models.
Journal ArticleDOI
Coronal properties of planet-bearing stars
TL;DR: In this article, the authors conduct a statistical analysis of stellar X-ray activity of all known planet-bearing stars within 30 pc distance for dependencies on planetary parameters such as mass and semimajor axis.
Journal ArticleDOI
Transit Observations of the Hot Jupiter HD 189733b at X-Ray Wavelengths
TL;DR: In this article, the authors reported a detection of the planetary transit in soft X-rays with a significantly deeper transit depth than observed in the optical. But they were unable to exclude several possible stellar origins for this deep transit, and additional observations will be necessary to fully exclude the possibility that coronal inhomogeneities influence the result.
