Ultracool Dwarfs in deep extragalactic surveys using the Virtual Observatory: ALHAMBRA and COSMOS
E. Solano, M. C. Gálvez-Ortiz, E. L. Martín +8
Ultracool dwarfs encompass a wide variety of compact stellar-like objects with spectra classified as late-M, L, T and Y. Most of them have been discovered using wide-field imaging…
Astrometric orbits of spectral binary brown dwarfs I: Massive T dwarf companions to 2M105921 and 2M080548
J. Sahlmann, A. J. Burgasser, D. C. Bardalez Gagliuffi +7
Near-infrared spectroscopic surveys have uncovered a population of short-period, blended-light spectral binaries composed of low-mass stars and brown dwarfs. These systems are amen…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
A highly unequal-mass eclipsing M-dwarf binary in the WFCAM Transit Survey
S. V. Nefs, J. L. Birkby, I. A. G. Snellen +6
In this paper we present the discovery of a highly unequal-mass eclipsing M-dwarf binary, providing a unique constraint on binary star formation theory and on evolutionary models f…
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…
Spectroscopic characterization of 78 DENIS ultracool dwarf candidates in the solar neighborhood and the Upper Sco OB association
E. L. Martin, N. Phan-Bao, M. Bessell +6
Aims: Low-resolution optical spectroscopic observations for 78 very low-mass star and brown dwarf candidates that have been photometrically selected using the DENIS survey point so…
