Based on observations obtained with UVES at VLT Kueyen 8.2 m telescope in programme 073.D-0473(A).

Of the 342 planets so far discovered orbiting other stars, 58 `transit' the stellar disk, meaning that they can be detected through a periodic decrease in the flux of starlight. The light from the star passes through the atmosphere of the planet, and in a few cases the basic atmospheric composition of the planet can be estimated. As we get closer

We report the discovery of burst oscillations from the intermittent accretion-powered millisecond pulsar (AMP) HETE J1900.1-2455, with a frequency ~1 Hz below the known spin frequency. The burst oscillation properties are far more similar to those of the non-AMPs and Aql X-1 (an intermittent AMP with a far lower duty cycle), than those of the AMPs

We analyse 1.5 μm spectropolarimetric observations of quiet regions at different positions on the solar surface. Neither the circular and linear polarization signals nor the area and amplitude asymmetries present a clear trend with the position on the Sun. This fact discards a network-like scenario for the internetwork magnetic fields. An

1005 objects selected from the IPHAS survey catalogue. Of these 721 are new PN candidates while 224 are known objects. Also listed is the information for counterparts in the 2MASS or UKIDSS surveys as well as the IRAS, MSX and NVSS catalogues. (1 data file).
