Magnetic fields in M dwarfs from the CARMENES survey
D. Shulyak, A. Reiners, E. Nagel +20
M dwarfs are known to generate the strongest magnetic fields among main-sequence stars with convective envelopes, but the link between the magnetic fields and underlying dynamo mec…
New ultracool subdwarfs identified in large-scale surveys using Virtual Observatory tools: II. SDSS DR7 vs UKIDSS LAS DR6, SDSS DR7 vs UKIDSS LAS DR8, SDSS DR9 vs UKIDSS LAS DR10, and SDSS DR7 vs 2MASS
N. Lodieu, M. Espinoza Contreras, M. R. Zapatero Osorio +4
We aim at developing an efficient method to search for late-type subdwarfs (metal-depleted dwarfs with spectral types >M5) to improve the current statistics. Our objectives are: im…
Constraints on the binary Properties of mid to late T dwarfs from Hubble Space Telescope WFC3 Observations
M. Aberasturi, A. J. Burgasser, A. Mora +4
We used HST/WFC3 observations of a sample of 26 nearby (20 pc) mid to late T dwarfs to search for cooler companions and measure the multiplicity statistics of brown dwarfs. Ti…
Search for bright nearby M dwarfs with Virtual Observatory tools
M. Aberasturi, J. A. Caballero, B. Montesinos +3
Using Virtual Observatory tools, we cross-matched the Carlsberg Meridian 14 and the 2MASS Point Source catalogs to select candidate nearby bright M dwarfs distributed over ~ 25,000…
Astrometric orbit of a low-mass companion to an ultracool dwarf
J. Sahlmann, P. F. Lazorenko, D. Segransan +4
Little is known about the existence of extrasolar planets around ultracool dwarfs. Furthermore, binary stars with Sun-like primaries and very low-mass binaries composed of ultracoo…
Discovery and characterisation of detached M-dwarf eclipsing binaries in the WFCAM Transit Survey
J. L. Birkby, S. V. Nefs, S. T. Hodgkin +17
We report the discovery of 16 detached M-dwarf eclipsing binaries with J<16 mag and provide a detailed characterisation of three of them, using high-precision infrared light curves…
