As GX 339-4 has started to leave the Low/Hard State (ATel #2545), we triggered the 2nd part of our INTEGRAL campaign on GX 339-4 in the declining phase of the hard X-ray band, as well as contemporaneous Swift observations. The source was observed by INTEGRAL for 158 ks between April 15 (01:57 UTC) and 17 (01:04 UTC), while Swift observed it four

In this paper, we present VLT/SINFONI integral field spectroscopy of RCW 34 along with Spitzer/IRAC photometry of the surroundings. RCW 34 consists of three different regions. A large bubble has been detected in the IRAC images in which a cluster of intermediate- and low-mass class II objects is found. At the northern edge of this bubble, an H II

The detection of the transiting extrasolar planet CoRoT-9b has just been reported (Deeg et al. 2010). With a semi-major axis of 0.41 astronomical unit on a quasi-circular orbit, this is the first transiting planet far enough from its parent star to have an extended Hill sphere (3.5 million kilometers in radius), as needed to form and sustain rings

Spectro-polarimetric observations with the Solar Optical Telescope onboard Hinode reveal the emission spectrum of the Fe I 630 nm lines at the solar limb. The emission shell extends for less than 1'' thereby making it extremely difficult to detect from ground-based observatories viewing the limb through the Earth's atmosphere. The linear

The theories of evolution of life on Earth have been based on the principle of storing and transmitting information of organisms in the genes, which according to the sequence of nucleotides could form proteins.

Context. The standard prescription of angular momentum loss in compact binaries assumes magnetic braking to be very efficient as long as the secondary star has a radiative core, but to be negligible if the secondary star is fully convective. This prescription has been developed to explain the orbital period gap observed in the orbital period
