TL;DR: The Stellar Imager (SI) as discussed by the authors is a UV-Optical, Space-Based Interferometer designed to enable 0.1 milli-arcsecond (mas) spectral imaging of stellar surfaces and of the Universe in general and asteroseismic images of stellar interiors.

TL;DR: In this paper, the authors derived an analytic solution for the minimization problem in the geometric Baade-Wesselink method, which allows deriving the distance and mean radius of a pulsating star by fitting its velocity curve and angular diameter measured interferometrically.

TL;DR: The first release of the Chandra Source Catalog (CSC) contains ~95,000 X-ray sources in a total area of 0.75% of the entire sky, using data from ~3900 separate ACIS observations of a multitude of different types of different sources as discussed by the authors.

TL;DR: An overview of Chandra X-ray observations of neutron stars can be found in this article, where the authors present an admittedly biased and overly brief review of these observations, highlighting some new discoveries made possible by the Observatory's unique capabilities, including the analysis of recent multiwavelength observations of the putative pulsar and its pulsar-wind nebula in the IC443 SNR.

TL;DR: In this article, the authors used PSF deconvolution techniques to carry out astrometry of the binary Cepheid Aa and Aa Aa, and found a dynamical mass of 3.45 +/- 0.75 µm.
