We report on RXTE observations of the neutron star transient currently active in Terzan 5 (also known as IGR J17480-2446; ATels #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2937, #2939, #2940, #2946), which has recently turned into a Z source (Altamirano et al., ATel #2952). The X-ray burst rate has increased gradually (see also ATels #2939,

An RXTE pointed observation of the ongoing outburst of of the transient source in the globular cluster Terzan 5 (ATEL #2919, #2920, #2922, #2924, #2929) began at approximately 2010-10-13 at 00:13 UTC, for an exposure of 3.2 ksec. This observation revealed strong pulsations at a barycentric frequency of 11.0452(2) Hz as well as one Type I X-ray

The study of cool atmospheres is currently a fruitful field of interaction between theorists developing better atmosphere models and observers discovering new cool objects and analysing their emission spectrum. Save for a few close binaries with known parallax and a dynamical mass determination, comparison of spectra to models is the only method

We triggered a Chandra ToO observation of the ongoing outburst of a transient source in the globular cluster Terzan 5 (ATel #2919, #2920, #2922, #2924, #2929, #2932, #2933, #2937, #2939, #2940, #2946, #2952, #2958). The 9.9 ks observation was taken with the ACIS S3 chip in imaging mode and began on 2010-10-24 at 19:30:29 UTC. Inspection of the new

CARMENES, Calar Alto high-Resolution search for M dwarfs with Exo-earths with a Near-infrared Echelle Spectrograph, is a study for a next-generation instrument for the 3.5 m Calar Alto Telescope to be designed, built, integrated, and operated by a consortium of nine German and Spanish institutions. Our main objective is finding habitable exoplanets

Transiting planet systems offer a unique opportunity to observationally constrain proposed models of the interiors (radius, composition) and atmospheres (chemistry, dynamics) of extrasolar planets. The spectacular successes of ground-based transit surveys (more than 60 transiting systems known to-date) and the host of multi-wavelength, spectro
