K2-136: A Hyades Binary Star with a Neptune-sized Planet [PDF]

, 2017
We report the discovery of a Neptune-size planet (Rp = 3.0 Re) in the Hyades Cluster. The host star is in a binary system, comprising a K5V star and M7/8V star with a projected separation of 40 AU.

Potential Importance of Binary Evolution in UV-Optical Spectral Fitting of Early-Type Galaxies

, 2013
Binaries are very common in galaxies, and more than half of Galactic hot subdwarf stars, which are thought as a possible origin of UV-upturn of old stellar populations, are found in binaries.

Evidence for a planetary mass third body orbiting the binary star KIC 5095269 [PDF]

, 2017
In this paper, we report the evidence for a planetary mass body orbiting the close binary star KIC 5095269. This detection arose from a search for eclipse timing variations among the more than 2,000 eclipsing binaries observed by Kepler.

How THC works: Explaining ligand affinity for, and partial agonism of, cannabinoid receptor 1

iScience
Summary: Interaction with cannabinoid receptor 1 (CB1) partially determines the bioactivity of the phytocannabinoids. Consequently, there has also been significant effort directed toward preparing synthetic cannabinoids with either enhanced agonistic or ...

Period Change of the Contact Binary AH Tauri [PDF]

Journal of Astronomy and Space Sciences, 2004
New BVRI photometric observations of the contact binary AH Tau were performed with the 61 cm reflector and a 2K CCD camera at the Sobaeksan Optical Astronomy Observatory during seven nights from September to December, 2001. A total of 144 times of minima

Dynamical population synthesis: Constructing the stellar single and binary contents of galactic field populations

, 2011
[abridged] The galactic field's late-type stellar single and binary population is calculated on the supposition that all stars form as binaries in embedded star clusters.

Discovery of a bright eclipsing cataclysmic variable [PDF]

, 2007
We report on the discovery of J0644+3344, a bright deeply eclipsing cataclysmic variable (CV) binary. Spectral signatures of both binary components and an accretion disk can be seen at optical wavelengths.

PRELIMINARY RESULTS OF MODELING OF LIGHT CURVES OF WW AND

Odessa Astronomical Publications, 2017
In this work we present the preliminary results of modeling of Olson’s lybv light curves of an Algol-type binary WW And. A model of a binary star containing an accretion disk around the primary star is deployed.

Binary Neutron Star Mergers After GW170817

Frontiers in Astronomy and Space Sciences, 2020
The first combined detection of gravitational waves and electromagnetic signals from a binary neutron star (BNS) merger in August 2017 (an event named GW170817) represents a major landmark in the ongoing investigation of these extraordinary systems.

Incompressible fluid binary systems with internal flows -- models of close binary neutron star systems with spin

, 1998
In this paper we have examined numerically exact configurations of close binary systems composed of incompressible fluids with internal flows.
