Orbital parameters of the microquasar LS I +61 303
New optical spectroscopy of the high-mass X-ray binary microquasar LS I +61 303 is presented. Eccentric orbital fits to our radial velocity measurements yield updated orbital parameters in goodExpand

A possible black hole in the γ-ray microquasar LS 5039
The population of high-energy and very high-energy γ-ray sources, detected with EGRET and the new generation of ground-based Cherenkov telescopes, forms a reduced but physically important sample.Expand

The initial–final mass relationship of white dwarfs revisited: effect on the luminosity function and mass distribution
The initial-final mass relationship connects the mass of a white dwarf with the mass of its progenitor in the main-sequence. Although this function is of fundamental importance to several fields inExpand

The distance to the Andromeda galaxy from eclipsing binaries
The cosmic distance scale largely depends on distance determinations to galaxies of the Local Group. In this sense, the Andromeda galaxy (M 31) is a key rung to better constrain the cosmic distanceExpand

Atmospheric Loss of Exoplanets Resulting from Stellar X-Ray and Extreme-Ultraviolet Heating
Past studies addressing the thermal atmospheric escape of hydrogen from hot Jupiters have been based on the planet's effective temperature, which, as we show here, is not physically relevant for lossExpand

Absolute Dimensions of the M-Type Eclipsing Binary YY Geminorum (Castor C): A Challenge to Evolutionary Models in the Lower Main Sequence*
We present new spectroscopic observations of the detached late-type double-lined eclipsing binary YY Geminorum (P = 0.814 day), a member of the Castor sextuple system and one of the benchmarks forExpand

Water vapour in the atmosphere of a transiting extrasolar planet
Water is predicted to be among the most abundant (if not the most abundant) molecular species after hydrogen in the atmospheres of close-in extrasolar giant planets (‘hot Jupiters’). Several attemptsExpand

M stars as targets for terrestrial exoplanet searches and biosignature detection.
The changing view of planets orbiting low mass stars, M stars, as potentially hospitable worlds for life and its remote detection was motivated by several factors, including the demonstration ofExpand

A correlation between the heavy element content of transiting extrasolar planets and the metallicity of their parent stars
Context. Nine extrasolar planets with masses between 110 and 430M⊕ are known to transit their star. The knowledge of their masses and radii allows an estimate of their composition, but uncertaintiesExpand

The Distance to the Large Magellanic Cloud from the Eclipsing Binary HV 2274
The distance to the Large Magellanic Cloud (LMC) is crucial for the calibration of the cosmic distance scale. We derive a distance to the LMC based on an analysis of ground-based photometry andExpand
