Infrared Spectroscopy of V838 Monocerotis in 2015 and 2022
T. R. Geballe, B. M. Kaminskiy, D. P. K. Banerjee +5
We report medium-resolution m spectroscopy obtained in 2015 and 2022 and high resolution m and m spectroscopy obtained in 2015 of V838 Mon…
Detection of Methane in the Closest Extreme Metal-poor T Dwarf WISEA J181006.18-101000.5
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. Martín +7
WISEA J181006.18-101000.5 (WISE1810) is the nearest metal-poor ultracool dwarf to the Sun. It has a low effective temperature and has been classified as extreme early-T subdwarf. H…
Optical constraints on the coldest metal-poor population
Jerry Jun-Yan Zhang, Nicolas Lodieu, Eduardo L. Martín +10
The coldest metal-poor population made of T and Y dwarfs are archaeological tracers of our Galaxy because they are very old and have kept the pristine material. The optical propert…
Primeval very low-mass stars and brown dwarfs -- VIII. The first age benchmark L subdwarf, a wide companion to a halo white dwarf
Z. H. Zhang, R. Raddi, A. J. Burgasser +12
We report the discovery of five white dwarf + ultracool dwarf systems identified as common proper motion wide binaries in the Gaia Catalogue of Nearby Stars. The discoveries includ…
Flare activity and photospheric analysis of Proxima Centauri
Ya. V. Pavlenko, A. Suarez Mascareno, R. Rebolo +3
We present the analysis of emission lines in high-resolution optical spectra of the planet-host star Proxima Centauri (Proxima) classified as a M5.5V\@. We carry out the detailed a…
Intermediate Resolution Near-Infrared Spectroscopy of 36 late-M Dwarfs
R. Deshpande, E. L. Martín, M. M. Montgomery +8
We present observations of 36 late-M dwarfs obtained with the KeckII/NIRSPEC in the J-band at a resolution of \sim20,000. We have measured projected rotational velocities, absolute…
