ABYSS. I. Targeting Strategy for the APOGEE and BOSS Young Star Survey in SDSS-V
The Astrophysical Journal Supplement Series, 2023 The fifth iteration of the Sloan Digital Sky Survey is set to obtain optical and near-infrared spectra of ∼5 million stars of all ages and masses throughout the Milky Way. As a part of these efforts, APOGEE and BOSS Young Star Survey (ABYSS) will observe

Interrelated main-sequence mass–luminosity, mass–radius, and mass–effective temperature relations [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Absolute parameters of 509 main-sequence stars selected from the components of detached-eclipsing spectroscopic binaries in the Solar neighbourhood are used to study mass-luminosity, mass-radius and mass-effective temperature relations (MLR, MRR and MTR).

The Astrophysical Journal, 2023 Asteroseismology has been used extensively in recent years to study the interior structure and physical processes of main-sequence stars. We consider prospects for using pressure modes (p-modes) near the frequency of maximum oscillation power to probe ...

The star formation activity of IllustrisTNG galaxies: main sequence, UVJ diagram, quenched fractions, and systematics [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We select galaxies from the IllustrisTNG hydrodynamical simulations ($M_{\rm stars}\gt 10^9 \, {\rm M}_\odot$ at 0 ≤ z ≤ 2) and characterize the shapes and evolutions of their UVJ and star formation rate–stellar mass (SFR–Mstars) diagrams.

Simulating the Sensitivity to Stellar Point Sources of Chandra X-Ray Observations
The Astrophysical Journal Supplement Series, 2023 The Chandra Cygnus OB2 Legacy Survey is a wide and deep X-ray survey of the nearby and massive Cygnus OB2 association. The survey has detected ∼8000 X-ray sources, the majority of which are pre-main-sequence X-ray-emitting young stars in the association ...

Hot Jupiters Are Destroyed by Tides While Their Host Stars Are on the Main Sequence [PDF]
Astronomical Journal, 2019 While cooler giant planets are often observed with nonzero eccentricities, the short-period circular orbits of hot Jupiters suggest that they lose orbital energy and angular momentum due to tidal interactions with their host stars. However, orbital decay

On the Relationship of the Degrees of Correspondence of Dialects and Distances
Languages, 2019 This study analyzes the relationship between the degrees of resemblance and distances between dialects based on several dialectological atlases. This analysis investigates various correspondence data with respect to total valid data in setting reference ...

XUE: Molecular Inventory in the Inner Region of an Extremely Irradiated Protoplanetary Disk
The Astrophysical Journal Letters, 2023 We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, which focuses on the characterization of planet-forming disks in massive star-forming regions.

Main sequence of star forming galaxies beyond the Herschel confusion limit [PDF]
Astronomy & Astrophysics, 2018 Context. Deep far-infrared (FIR) cosmological surveys are known to be affected by source confusion, causing issues when examining the main sequence (MS) of star forming galaxies.
