We report the detection with the BeppoSAX Wide Field Cameras of a superburst from 4U 1254-69. The superburst is preceded by a normal type-I X-ray burst, has a...
A survey for pulsating subdwarf B stars with the Nordic Optical Telescope
Context. A search programme for pulsating subdwarf B stars was conducted with the Nordic Optical Telescope on La Palma over 59 nights between 1999 and 2009...
A survey of IRAS young stellar object candidates. Searching for large-scale Herbig-Haro objects
Context. Jets and outflows are associated with young stellar objects across the stellar mass spectrum, from brown dwarf protostars to massive Ae/Be stars...
A synthetic stellar polarization atlas from 400 to 1000 nm
Context: With the development of new polarimeters for large telescopes, the spectro-polarimetric study of astrophysical bodies is becoming feasible and, indeed...
A temperate exo-Earth around a quiet M dwarf at 3.4 parsec
The combination of high-contrast imaging and high-dispersion spectroscopy, which has successfully been use to detect the atmosphere of a giant planet, is one of...
A temperature inversion with atomic iron in the ultra-hot dayside atmosphere of WASP-189b
Temperature inversion layers are predicted to be present in ultra-hot giant planet atmospheres. Although such inversion layers have recently been observed in...
A tentative detection of He I in the atmosphere of GJ 1214 b
The He I λ10833 Å triplet is a powerful tool for characterising the upper atmosphere of exoplanets and tracing possible mass loss. Here, we analysed one transit...
A test case of stellar evolution: the eclipsing binary EK Cephei. A system with accurate dimensions, apsidal motion rate and lithium depletion level.
EK Cep is a double-lined eclipsing binary system with unique characteristics. Accurate absolute dimensions are available, a good determination of the surface...
A large-scale three-dimensional model of Galactic extinction is presented based on the Galactic dust distribution model of citet{DS01}. The extinction AV to any...
