The ultracool eld dwarfs luminosity function from the Canada-France Brown Dwarf Survey
C. Reyle, P. Delorme, X. Delfosse +4
The Canada-France Brown Dwarf Survey is a wide eld survey for cool brown dwarfs conducted with the MegaCam camera on the CFHT telescope. Our objectives are to nd ultracool brown dw…
Stellar Age Estimation from ~3 Myr to ~3 Gyr
Lynne Hillenbrand, Eric Mamajek, John Stauffer +3
We present recent progress on quantitative estimation of stellar ages using ind icators such as theoretical evolutionary tracks, rotation, rotation-driven chrom ospheric and corona…
A search for wide brown dwarf companions to stars within 10pc
Marin Treselj, Andreas Seifahrt, Klaus-Werner Hodapp +2
We present the first results of a large imaging survey to identify wide brown dwarf companions to stars within 10 pc. We have performed a deep (H-band limit ~ 19.0 mag), wide field…
Activity and rotation of low mass stars in young open clusters
Andreas Seifahrt, Ansgar Reiners, Aleks Scholz +1
We present first results from a multi-object spectroscopy campaign in IC2602, the Hyades, the Pleiades, and the Coma cluster using VLT/FLAMES. We analysed the data for radial veloc…
The mass-radius relationship from solar-type stars to terrestrial planets: a review
G. Chabrier, I. Baraffe, J. Leconte +2
In this review, we summarize our present knowledge of the behaviour of the mass-radius relationship from solar-type stars down to terrestrial planets, across the regime of substell…
Welcome back, Polaris the Cepheid
H. Bruntt, A. J. Penny, D. Stello +2
For about 100 years the amplitude of the 4-day pulsation in Polaris has decreased. We present new results showing a significant increase in the amplitude based on 4.5 years of cont…
