We report on the serendipitous discovery of a Herbig-Haro flow close to the pre-main sequence system HV Tauri. Low resolution spectra indicate a high excitation...

PublicaciónLithium abundances in classical and weak T Tauri stars
A study on the lithium abundance in 36 T Tauri stars (mass range 0.4-2.25 solar masses), partly based on high-dispersion spectra taken with the Isaac Newton...
PublicaciónLithium in T Tauri stars
The lithium abundance in 26 T Tauri stars is derived using data taken at the Isaac Newton Telescope and data from literature. The aim is to understand the...
PublicaciónLithium in the pre-main sequence triple system UX Tauri
High-resolution spectra (range 655-675 nm) are presented of the pre-main sequence triple system UX Tau. Favorable seeing conditions allowed detection of the...
PublicaciónNear infrared-IRAS candidates for molecular outflows in LYNDS clouds
The IRAS Point Source Catalog was cross-correlated with the Lynds Catalog of Dark Clouds to find bright IR sources with 100-micron fluxes higher than their...
PublicaciónOn the evolutionary status of two very active visual binaries
HD 36705 (AB Doradus) and HD 155555 (V824 Ara) are two nearby very active cool stars. Both have strong Li I (lambda)6708 resonance lines, implying high surface...
PublicaciónOn the post-T-Tauri nature of late-type visual companions to B-type stars
We report on intermediate-to-high resolution spectroscopy and standard broadband photometry of late-type visual companions to early-type stars. Our program...
PublicaciónPre-main sequence lithium burning. 1: Weak T Tauri stars
We report high-resolution spectroscopic observations for a sample of 38 T Tauri stars (TTS), complemented by UBVRI photometry of 13 TTS, and CCD VRI photometry...
