Estimation of the XUV radiation onto close planets and their evaporation
Context. The current distribution of planet mass vs. incident stellar X-ray flux supports the idea that photoevaporation of the atmosphere may take place in close-in planets. Integrated effects haveExpand

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

Parameters of Herbig Ae/Be and Vega-type stars ⋆
Context. This work presents the characterization of 27 young early-type stars, most of them in the age range 1‐10 Myr, and three ‐suspected‐ hot companions of post-T Tauri stars belonging to theExpand

DUst around NEarby Stars. The survey observational results
Context. Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system counterparts are the asteroid and Edgeworth-KuiperExpand

A scenario of planet erosion by coronal radiation
Context. According to theory, high-energy emission from the coronae of cool stars can severely erode the atmospheres of orbiting planets. No observational tests of the long-term erosion effects haveExpand

A spectroscopy study of nearby late-type stars, possible members of stellar kinematic groups
Context. Nearby late-type stars are excellent targets for seeking young objects in stellar associations and moving groups. The origin of these structures is still misunderstood, and lists of movingExpand

Kuiper belts around nearby stars
Context. The existence of dusty debris disks around a large fraction of solar type main-sequence stars, inferred from excess far-IR and submillimetre emission compared to that expected from stellarExpand

EXPORT: Spectral classification and projected rotational velocities of Vega-type and pre-main sequence stars
In this paper we present the rst comprehensive results extracted from the spectroscopic campaigns car- ried out by the EXPORT (EXoPlanetary Observational Research Team) consortium. During 1998{1999,Expand

Molecular Gas in Debris Disks around Young A-type Stars
According to the current paradigm of circumstellar disk evolution, gas-rich primordial disks evolve into gas-poor debris disks compose of second-generation dust. To explore the transition betweenExpand

The powering sources of the molecular outflows in the AFGL 437, AFGL 5142, and AFGL 5157 regions
VLA 3.6 cm continuum and water maser observations are presented toward the central region of three molecular outflows for which the position of the powering sources was not clearly established: AFGLExpand
