    Limits to the planet candidate GJ 436c
    We report on H-band, ground-based observations of a transit of the hot Neptune GJ 436b. Once combined to achieve sampling equivalent to archived observations...

    Limits to the presence of transiting circumbinary planets in CoRoT Data
    Aims: During its flight phase, from 2007-2012, the CoRoT mission delivered light curves for over 2000 eclipsing binaries. Data from the Kepler mission have...

    Lithium in the Hyades L5 brown dwarf 2MASS J04183483+2131275
    Aims: From the luminosity, effective temperature and age of the Hyades brown dwarf 2MASS J04183483+2131275 (2M0418), substellar evolutionary models predict a...

    Local Cosmology from Isolated Dwarfs: the derivation of star formation histories.
    The color-magnitude diagram (CMD) is the most powerful tool to derive quantitative star formation histories (SFHs) of complex stellar systems which host...
