Half a Million M Dwarf Stars Characterized Using Domain-Adapted Spectral Analysis
Shuo Zhang, Hua-Wei Zhang, Yuan-Sen Ting +5
We present fundamental atmospheric parameters (Teff and log g) and metallicities ([M/H]) for 507,513 M dwarf stars using low-resolution spectra (R~1800) from LAMOST DR10. By employ…
Near-infrared spectroscopic characterisation of Gaia ultra-cool dwarf candidates; Spectral types and peculiarities
T. Ravinet, C. Reylé, N. Lagarde +10
Context: The local census of very low-mass stars and brown dwarfs is crucial to improving our understanding of the stellar-substellar transition and their formation history. These…
Primeval very low-mass stars and brown dwarfs - IV. New L subdwarfs, Gaia astrometry, population properties, and a blue brown dwarf binary
Z. H. Zhang, M. C. Galvez-Ortiz, D. J. Pinfield +13
We present 27 new L subdwarfs and classify five of them as esdL and 22 as sdL. Our L subdwarf candidates were selected with the UKIRT Infrared Deep Sky Survey and Sloan Digital Sky…
Primeval very low-mass stars and brown dwarfs - III. The halo transitional brown dwarfs
Z. H. Zhang, D. J. Pinfield, M. C. Galvez-Ortiz +11
We report the discovery of an esdL3 subdwarf, ULAS J020858.62+020657.0, and a usdL4.5 subdwarf, ULAS J230711.01+014447.1. They were identified as L subdwarfs by optical spectra obt…
Temperature constraints on the coldest brown dwarf known WISE 0855-0714
J. C. Beamín, V. D. Ivanov, A. Bayo +10
Context. Nearby isolated planetary mass objects are beginning to be discovered, but their individual properties are poorly constrained because their low surface temperatures and st…
A library of near-infrared integral field spectra of young M-L dwarfs
M. Bonnefoy, G. Chauvin, A. -M. Lagrange +5
We present a library of near-infrared (1.1-2.45 microns) medium-resolution (R~1500-2000) integral field spectra of 15 young M6-L0 dwarfs, composed of companions with known ages and…
