In this paper, we present deep high-quality photometry of globular cluster systems (GCSs) belonging to five early-type galaxies, covering a range of mass and environment. Photometric data were obtained with the Gemini North and Gemini South telescopes in the filter passbands g', r' and i'. The combination of these filters with good seeing

FK Com (G5 III) is an ultrafast-rotating single yellow giant. It is the eponymous member of its class, and is suspected to have been a coalesced binary that has spun up. Here we present preliminary results from a multi-wavelength campaign we have carried out in April-May 2011. We observe the corona with X-rays with the high-resolution HETG

We present the first entirely ground-based astrometric determination of the proper motion for the Fornax Local Group dwarf spheroidal satellite galaxy of the Milky Way (MW), using charge-coupled device data acquired with the ESO 3.5 m New Technology Telescope at La Silla Observatory in Chile. Our unweighted mean from five quasar fields in the

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
