Spitzer/infrared spectrograph (IRS) spectra from 5 to 37 μm for a complete sample of 31 R Coronae Borealis stars (RCBs) are presented. These spectra are combined with optical and near-infrared photometry of each RCB at maximum light to compile a spectral energy distribution (SED). The SEDs are fitted with blackbody flux distributions and estimates

Ingenio/SEOSAT is the flagship mission for the Spanish Space Plan 2007-2011, as is currently under development by a Spanish industrial consortium in the framework of an ESA contract. Ingenio/SEOSAT is a multi-spectral high-resolution optical satellite for Earth Remote Sensing, designed to provide imagery to different Spanish civil, institutional

With a mass of 7.4 Earth masses and radius of 1.6 Earth radii, CoRoT-7b is among the smallest transiting planets found to date. Due to its small size, the transit signal is very shallow, which makes the estimation of the planetary parameters from the light curve challenging. We carry out a Bayesian analysis of the CoRoT-7b lightcurve using a

Detection of planets in the habitable zone is one of the key drivers of the exoplanet science community. We present a detailed strategy for such detection around L and T dwarfs. We plan to implement the outcome of the analysis as a transit survey to search for planets around known L and T dwarfs. Understanding of the variability of these cool

A new transient X-ray source was discovered in the 2011 August 26 Chandra ACIS observation of M31 (OBSID 12973), at RA = 00:42:11.37 DEC = +41:04:25.51. This system is likely to be a low mass X-ray binary with a black hole primary. The emission spectrum contained ~250 net source counts, and was well described by a power law with photon index 1.4 ±

We present a chemical abundance analysis of the secondary star in the black hole binary V404 Cygni, using Keck I/High Resolution Spectrometer. We adopt a χ2-minimization procedure to derive the stellar parameters, taking into account any possible veiling from the accretion disk. With these parameters we determine the atmospheric abundances of O, Na
