Low-mass contact binaries: orbital stability at extreme low mass ratios [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT With the ever-increasing number of light-curve solutions of contact binary systems, an increasing number of potential bright red nova progenitors are being reported. There remains, however, only one confirmed event. In this study, we undertake a comprehensive review of the orbital stability of contact binary systems, considering

Searches for low-mass dimuon resonances [PDF]

open access: yesJournal of High Energy Physics, 2020
Searches are performed for a low-mass dimuon resonance, X, produced in proton-proton collisions at a center-of-mass energy of 13 TeV, using a data sample corresponding to an integrated luminosity of 5.1 fb −1 and collected with the LHCb detector.

Benchmark low-mass objects in Moving Groups [PDF]

open access: diamondEPJ Web of Conferences, 2013
In order to compile a sample of ultracool dwarfs that will serve as benchmarks for testing theoretical formation and evolutionary models, we selected low-mass cool (>M7) objects that are potentially members of five known young Moving Groups in the solar ...

Stellar Mass Calibrations for Local Low-mass Galaxies

open access: yesThe Astrophysical Journal
The stellar masses of galaxies are measured from integrated light via several methods—however, few of these methods were designed for low-mass ( M _⋆ ≲ 10 ^8 M _⊙ ) “dwarf” galaxies, whose properties (e.g., stochastic star formation, low metallicity ...

Lyman continuum leakage from low-mass galaxies with M⋆ < 108 M⊙ [PDF]

open access: yes, 2021
We present observations with the Cosmic Origins Spectrograph onboard the Hubble Space Telescope of nine low-mass starforming galaxies at redshifts, z, in the range 0.3179 – 0.4524, with stellar masses M★ < 108 M and very high specific star-formation ...

Dislocation and disclination densities in experimentally deformed polycrystalline olivine [PDF]

open access: yesEuropean Journal of Mineralogy, 2023
We report a comprehensive data set characterizing and quantifying the geometrically necessary dislocation (GND) density in the crystallographic frame (ραc) and disclination density (ρθ) in fine-grained polycrystalline olivine deformed in uniaxial ...

Hidden Little Monsters: Spectroscopic Identification of Low-mass, Broad-line AGNs at z > 5 with CEERS

open access: yesAstrophysical Journal Letters, 2023
We report on the discovery of two low-luminosity, broad-line active galactic nuclei (AGNs) at z > 5 identified using JWST NIRSpec spectroscopy from the Cosmic Evolution Early Release Science (CEERS) survey.

The coronal temperatures of low-mass main-sequence stars [PDF]

open access: bronze, 2015
Aims. We study the X-ray emission of low-mass main-sequence stars to derive a reliable general scaling law between coronal temperature and the level of X-ray activity. Methods.

Postmerger Mass Ejection of Low-mass Binary Neutron Stars [PDF]

open access: yesAstrophysical Journal, 2020
We study the postmerger mass ejection of low-mass binary neutron stars (NSs) with the system mass of 2.5 M ⊙ and subsequent nucleosynthesis by performing general-relativistic, neutrino-radiation viscous-hydrodynamics simulations in axial symmetry.
