Spectroscopy and kinematics of low-mass members of young moving groups
M. C. Galvez-Ortiz, J. R. A. Clarke, D. J. Pinfield +8
We study a target sample of 68 low-mass objects (with spectral types in the range M4.5-L1) previously selected via photometric and astrometric criteria, as possible members of five…
A high-resolution spectroscopic survey of late-type stars: chromospheric activity, rotation, kinematics, and age
J. Lopez-Santiago, D. Montes, M. C. Galvez-Ortiz +5
Aims: We present a compilation of spectroscopic data from a survey of 144 chromospherically active young stars in the solar neighborhood which may be used to investigate different…
Discovery of the first wide L dwarf + giant binary system and eight other ultra-cool dwarfs in wide binaries
Z. H. Zhang, D. J. Pinfield, A. C. Day-Jones +11
We identify 806 ultra-cool dwarfs from their SDSS riz photometry (of which 34 are newly discovered L dwarfs) and obtain proper motions through cross matching with UKIDSS and 2MASS.…
