Observations of Complex H, a High Velocity Cloud Close to the Galactic Plane
Using 21 cm observations of Complex H with the Green Bank Radio Telescope, we have derived its LSR velocity of ˜ 200 km s-1 and an H I mass of 7.5× 107 M&sun...
Observations of Cygnus X-2 with IUE: Ultraviolet results from a multiwavelength campaign
The observations of the low-mass x ray binary, Cyg X-2, taken with the International Ultraviolet Explorer (IUE) in a campaign conducted in June and October of...
We present high resolution long-slit spectra of HH 444 and numerical simulations for this Herbig-Haro object. From the comparison between observations and...
Observations of Li-rich giant stars in the Galaxy and in the Magellanic Clouds
The Lithium content in stars is very sensitive to the internal stellar conditions. Indeed, Lithium is readily destroyed in the interiors of low-mass main...
Preliminary results are presented of spectroscopic analysis of ten young stars in OB associations using high resolution spectra and NLTE calculations. From the...
