We report follow-up observations confirming the near-infrared (NIR) counterpart to the X-ray transient XTE J1747-274/IGR J17473-2721 (ATEL #467, #498). A Ks=16.2 mag candidate was suggested in ATEL #521 on the basis of its coincidence with the Chandra localization for the X-ray source. The candidate appeared extended and/or blended with a nearby

We present the motivation, design and current status of the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). Using the high resolution spectroscopic facilities available at Spanish observatories, OCCASO will derive chemical abundances in a sample of 20 to 25 OCs older than 0.5 Gyr. This sample will be used to study in

We analyse the poorly studied open cluster King 1 in the second Galactic quadrant. From wide-field photometry, we have studied the spatial distribution of this cluster. We determined that the centre of King 1 is located at α2000 = 00h22m and δ2000 = +64°23΄. By parameterizing the stellar density with a King profile, we have obtained a central

Using data obtained with the ESO-Very Large Telescope, we have performed a deep optical and NIR photometric study of the fields of three Accreting Millisecond X-ray Pulsars (XTE J1814-338, XTE J0929-314 and XTE J1807-294) during quiescence in order to look for the presence of a variable counterpart. If suitable candidates are found, we also carried

In this presentation, we apply the Lava-ocean model that has been proposed for planets of the class of CoRoT-7b, i.e. rocky planets at a few stellar radii from their star, since Kepler-10b is a typical member of this family. The model predicts that the light from the planet has an important emission component in addition to the reflected one, even

Near-Earth asteroid 101955 (1999 RQ36; henceforth RQ36) is particularly interesting. It's especially accessible to spacecraft and is the primary target of NASA's OSIRIS-REx sample return mission; it's also a potentially hazardous asteroid (Milani et al. 2009). We combine dynamical and spectral information to identify the most likely main-belt
