TL;DR: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) as discussed by the authors is a very large-scale cosmological survey with a 2.5m telescope and a 4.7 sq.deg camera with 1.2Gpix.

TL;DR: In this article, the authors presented the results of prompt optical follow-up of the electromagnetic counterpart of the GW170817 by the Transient Optical Robotic Observatory of the South Collaboration.
Journal ArticleDOI
The X-ray emission of the γ Cassiopeiae stars
TL;DR: In this paper, the authors classified the γ Cas stars as the prototype of a class of stars that emit hard thermal X-rays, i.e., stars with light curves showing variability on a few broadly defined timescales and spectra indicative of an optically thin plasma consisting of one or more hot thermal components.
Journal ArticleDOI
The relationship between γ Cassiopeiae’s X-ray emission and its circumstellar environment - II. Geometry and kinematics of the disk from MIRC and VEGA instruments on the CHARA Array

TL;DR: In this article, the authors used the CHARA interferometer to obtain a global disk geometry and spectrally dispersed visibility modulus and phases within the Hα emission line, which enables them to study the kinematics within γ Cas's disk.
Journal ArticleDOI

TL;DR: In this article, a neural network-based photometry pipeline was developed to estimate the effective temperature, T eff, and metallicity, [Fe/H], for a large subset of stars in the J-PLUS footprint.
