New stellar members of the Coma Berenices open star cluster
We present the results of a survey of the Coma Berenices open star cluster (Melotte 111), undertaken using proper motions from the USNO-B1.0 and photometry from the 2MASS Point Source catalogues. We have identified 60 new candidate members with masses in the range 1.007M⊙<M<0.269M⊙. For each we have estimated a membership probability by extracting control clusters from the proper motion vector ...
متن کاملLithium in the Coma Berenices open cluster
Lithium abundances, radial velocities, and rotational velocities are reported for 20 candidate F, G and K stars of the sparse Coma Berenices open cluster. All the stars are proper-motion selected, and our radial velocities support the membership credentials of at least 12 of the candidates. Combining our data with that in the literature, we have a close-to-complete census of Li abundances for l...
متن کاملThe Stellar Populations of Praesepe and Coma Berenices
We present the results of a stellar membership survey of the nearby open clusters Praesepe and Coma Berenices. We have combined archival survey data from the SDSS, 2MASS, USNOB1.0, and UCAC-2.0 surveys to compile proper motions and photometry for ∼5 million sources over 300 deg. Of these sources, 1010 stars in Praesepe and 98 stars in Coma Ber are identified as candidate members with probabilit...
متن کاملTurning the Tides on the Ultra-Faint Dwarf Spheroidal Galaxies: Coma Berenices and Ursa Major
We present deep CFHT/MegaCam photometry of the ultra-faint Milky Way satellite galaxies: Coma Berenices (ComBer) and Ursa Major II (UMa II). These data extend to r ∼ 25, corresponding to 3 mag below the mainsequence turn-offs in these galaxies. We robustly calculate a total luminosity of MV = −3.8 ± 0.6 for ComBer and MV = −3.9 ± 0.5 for UMa II, in agreement with previous results and confirming...
متن کاملSpectroscopically confirmed brown dwarf members of Coma Berenices and the Hyades
Wehave obtained lowandmedium-resolution spectra of nine brown dwarf candidatemembers of Coma Berenices and the Hyades using SpEX on the NASA InfraRed Telescope Facility and Long Slit Intermediate Resolution Infrared Spectrograph on the William Herschel Telescope. We conclude that seven of these objects are indeed late M or early L dwarfs, and that two are likely members of Coma Berenices and fo...
