Globular cluster chemistry in fast rotating dwarf stars belonging to intermediate age open clusters [PDF]
, 2018 (shortened) The peculiar chemistry observed in the multiple populations of Galactic globular clusters is not generally found in other systems like dwarf galaxies and open clusters, and at the moment no model can fully explain its presence.

Eclipsing Binaries in Multiple Star Systems [PDF]
Symposium - International Astronomical Union, 1992 Although the majority of the known eclipsing binaries are in systems which consist of only the two eclipsing components, a significant number of them do occur as components of triple star systems or higher order multiple star systems. In this context this term is restricted to those systems whose components are in closed orbits.

Combined Nucleosynthetic Yields of Multiple First Stars
, 2016 Modern numerical simulations of the formation of the first stars predict that the first stars formed in multiples. In those cases, the chemical yields of multiple supernova explosions may have contributed to the formation of a next generation star.

Hot Magnetic Stars in Exotic Multiple Systems [PDF]
EPJ Web of Conferences, 2020 A strong and stable magnetic field covering the whole surface is a landmark of chemically peculiar or CP stars. To explain the origin of mag- netic stars, several hypotheses were proposed, which depending on the mech- anism and time of formation can be ...

Extrasolar planets in stellar multiple systems
, 2012 Analyzing exoplanets detected by radial velocity or transit observations, we determine the multiplicity of exoplanet host stars in order to study the influence of a stellar companion on the properties of planet candidates.

Pr��fer $\star$--multiplication domains and $\star$--coherence
, 2006 The purpose of this paper is to deepen the study of the Pr fer $\star$--multiplication domains, where $\star$ is a semistar operation. For this reason, in Section 2, we introduce the $\star$--domains, as a natural extension of the $v$--domains, where $v$ is the classical Artin's divisorial operation.

A New Catalog of Am-type Chemically Peculiar Stars Based on LAMOST
The Astrophysical Journal Supplement Series, 2023 A total of about 21,600 Am candidates were detected with the MKCLASS code based on the low-resolution spectra of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data Releases 8 (v1.0), 9 (v0), and 10 (v0), which greatly expands the database

Multiplicity of late-type B stars with HgMn peculiarity
, 2010 Observations at various wavelengths of late B-type stars exhibiting strong overabundances of the chemical elements Hg and Mn in their atmospheres indicate that these stars are frequently found in binary and multiple systems.

Ground-layer wavefront reconstruction from multiple natural guide stars [PDF]
, 2007 Observational tests of ground layer wavefront recovery have been made in open loop using a constellation of four natural guide stars at the 1.55 m Kuiper telescope in Arizona.

Statistics Of Multiple Stars [PDF]
International Astronomical Union Colloquium, 2004 AbstractThe statistics of stellar systems of multiplicity three and higher is reviewed. They are frequent, 0.15−0.25 of all stellar systems. Some 700 multiples are expected among the 3383 stars of spectral type F, G, and K within 50 pc, while only 76 of them are actually known.
