New magnetic chemically peculiar stars
TL;DR: In this article, the authors used spectrophotometry to detect magnetic chemically peculiar (CP) stars among objects with large depressions in the continuum, including HDE 293764, BD+17°3622, HD 169887, HDE 231054 and HDE 338226.

Speckle Interferometry of New and Problem Hipparcos Binaries. II. Observations Obtained in 1998-1999 from McDonald Observatory
TL;DR: The Hipparcos satellite made measurements of over 9734 known double stars, 3406 new double stars and 11,687 unresolved but possible double stars as discussed by the authors, which made it an efficient means to confirm these systems from the ground.

TL;DR: In this paper, the detection and characterisation of IGWs in photometric observations of stars born with convective cores (M > 1.5 M$_{\odot}$) and parameterise the low-frequency power excess caused by IWs using an MCMC numerical scheme within a Bayesian framework.

Dominic M. Bowman,Conny Aerts,Conny Aerts,Cole Johnston,M. G. Pedersen,Tamara M. Rogers,Tamara M. Rogers,P. V. F. Edelmann,Sergio Simón-Díaz,Sergio Simón-Díaz,T. Van Reeth,T. Van Reeth,B. Buysschaert,B. Buysschaert,Andrew Tkachenko,Santiago Andrés Triana +15 more
TL;DR: In this article, the authors used the most recent CoRoT light curves for a sample of O, B, A and F stars, and parameterized the morphology of the flux contribution of IGWs in Fourier space using an MCMC numerical scheme within a Bayesian framework.

Astrophysics in 1999
TL;DR: The year 1999 saw the arrival of a star with three planets, a universe with three parameters, and a solar corona that could be heated at least three ways as mentioned in this paper, and there were at least 3 papers on every question that has ever been asked in astrophysics, from "Will the Universe expand forever?" to "Does mantle convection occur in one or two layers?" The answers generally were, "Yes, "No, and none of the above," to each of the questions.

TL;DR: The ESA Hipparcos satellite made measurements of over 12,000 double stars and discovered 3406 new systems as discussed by the authors, including a total of 11,687 "problem stars" that did not provide the classical parameters of separation and position angle (ρ, θ) but were the so-called problem stars, flagged "G, "O, "V, or "X" (field H59 of the main catalog).

Speckle Interferometry at the US Naval Observatory. II.
TL;DR: In this article, position angles and separations resulting from 2406 speckle interferometric observations of 547 binary stars are tabulated, with random errors estimated to be 14 mas in separation and 052/ρ in position angle, where ρ is the separation in arcseconds.
