Dynamical investigations of the multiple stars
Open Astronomy, 2017 Two multiple stars - the quadruple star - Bootis (ADS 9173) and the triple star T Taury were investigated. The visual double star - Bootiswas studied on the basis of the Pulkovo 26-inch refractor observations 1982-2013.

Euler-Apéry Type Multiple Zeta Star Values and Multiple t-Star Values
WSEAS TRANSACTIONS ON MATHEMATICS, 2022 By introducing an extra binomial factor in the summands of multiple zeta star series, we can define the Euler-Apéry type multiple zeta star series. Their convergent values at positive integers are called Euler-Apéry type multiple zeta star values. In this paper we establish several recurrence relations about these values and a parametric variant by the

CCD measurements of double and multiple stars at NAO Rozhen: II [PDF]
Serbian Astronomical Journal, 2006 Using the 2-m telescope of the Bulgarian National Astronomical Observatory at Rozhen observations of twenty multiple stars were carried out during one whole night - October 30/31, and, also, during the first half of the next one - October 31. 2005.

Dust Around T Tauri Stars [PDF]
Journal of Astronomy and Space Sciences, 2011 To reproduce the multiple broad peaks and the fine spectral features in the spectral energy distributions (SEDs) of T Tauri stars, we model dust around T Tauri stars using a radiative transfer model for multiple isothermal circumstellar dust shells. We

Towards multiple-star population synthesis [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 The multiplicities of stars, and some other properties, were collected recently by Eggleton & Tokovinin, for the set of 4559 stars with Hipparcos magnitude brighter than 6.0 (4558 excluding the Sun). In this paper I give a numerical recipe for constructing, by a Monte Carlo technique, a theoretical ensemble of multiple stars that resembles the ...

Multiple Stellar Populations in Metal-poor Globular Clusters with JWST: A NIRCam View of M92
The Astrophysical Journal, 2023 Recent work on metal-intermediate globular clusters (GCs) with [Fe/H] = −1.5 and −0.75 has illustrated the theoretical behavior of multiple populations in photometric diagrams obtained with the JWST.

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

A Survey of Herbig Ae/Be Multiplicity
The Astronomical Journal, 2023 Although the majority of Herbig Ae/Be (HAEBE) stars are likely multiple systems, relatively few multiples have been identified. We aim to create a statistically significant survey of HAEBE multiplicity as a function of stellar mass, to shed light on ...

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.
