The new X-ray transient MAXI J1836-194 is a black hole candidate X-ray binary (BHXB; ATel #3611, #3613, #3628 #3652). Its X-ray spectrum was seen to soften (ATel #3618, #3652) but the X-ray flux has recently decayed and the spectrum has hardened (see link below for the light curve and evolution in the X-ray hardness-intensity diagram).

We perform a Bayesian parameter inference in the context of resonantly damped transverse coronal loop oscillations. The forward problem is solved in terms of parametric results for kink waves in one-dimensional flux tubes in the thin tube and thin boundary approximations. For the inverse problem, we adopt a Bayesian approach to infer the most

The preliminary results of a multisite photometric campaign on the Pleiades Delta Scuti variable V650 Tauri are reported. The star was observed photometrically for 14 days during 2008 November from three observatories distributed in Longitude around the Earth. As a result of the preliminary analysis we have detected in V650 Tauri at least nine

Context. The evolved main-sequence Sun-like stars KIC 10273246 (F-type) and KIC 10920273 (G-type) were observed with the NASA Kepler satellite for approximately ten months with a duty cycle in excess of 90%. Such continuous and long observations are unprecedented for solar-type stars other than the Sun. Aims: We aimed mainly at extracting estimates

Our photometric observations of 18 mainbelt binary systems in more than one apparition revealed a strikingly high number of 15 having positively re-observed mutual events in the return apparitions. Our simulations of the survey showed that the data strongly suggest that poles of mutual orbits between components of binary asteroids are not

El descubrimiento de más de 500 planetas extrasolares nos ha brindado la posibilidad de estudiar en detalle las estrellas que albergan dichos planetas. La determinación de abundancias químicas proporciona información valiosa no sólo de las atmósferas de las estrellas sino también de los procesos que ocurren en el interior de las mismas y de cómo se
