This study is an investigation of the stellar density profile of the Galactic disc in the anticentre direction. We select over 40000 early A stars from INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) photometry in the Galactic longitude range 160° l 200° close to the equatorial plane (-1° b +1°). We then compare their

We measure the angle between the planetary orbit and the stellar rotation axis in the transiting planetary system CoRoT-1, with new HIRES/Keck and FORS/VLT high-accuracy photometry. The data indicate a highly tilted system, with a projected spin-orbit angle λ = 77° +/- 11°. Systematic uncertainties in the radial velocity data could cause the actual

Spectral energy distributions (SEDs) of the central few tens of parsec region of some of the nearest, most well-studied, active galactic nuclei (AGN) are presented. These genuine AGN-core SEDs, mostly from Seyfert galaxies, are characterized by two main features: an infrared (IR) bump with the maximum in the 2-10μm range and an increasing X-ray

Solar gravity modes (or g modes)—oscillations of the solar interior on which buoyancy acts as the restoring force—have the potential to provide unprecedented inference on the structure and dynamics of the solar core, inference that is not possible with the well-observed acoustic modes (or p modes). The relative high amplitude of the g-mode

The position of the recently discovered transient gamma-ray source J0109+6134 (ATEL #2414) lies within the footprints of the IPHAS (Drew et al. 2005, MNRAS, 362, 753; http://www.iphas.org) and UVEX (Groot et al. 2009, MNRAS, 399, 323) surveys of the northern Galactic plane. Paredes et al. (ATEL #2421) have already suggested an optical counterpart
