A Herbig-Haro flow in HV Tauri
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...

PublicaciónA search for new objects in the transition phase between AGB-stars and planetary nebulae
Preliminary results are presented from a spectroscopy survey of IRAS sources with colors similar to those of planetary nebulae. Two new planetary nebulae, some...

PublicaciónCO mapping of bipolar outflows
The paper presents CO and (C-13)O J = 2-1 spectra and mapping of bipolar outflows, acquired with the 12-m NRAO antenna at Kitt Peak, for the following sources...

PublicaciónISO-SWS Observations on Proto-Planetary System Candidates
We present a preliminary analysis of ISO-SWS spectra of a sample of Vega-type and pre-main sequence stars, which were observed from the ground in a project...

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...

PublicaciónPre-main sequence lithium burning. 2: Pleiades low mass stars
As part of a continuing study of the lithium abundances in pre-main sequence (PMS) low mass stars, we present Li observations for 13 K-type and 3 M-type stars...

PublicaciónSpectroscopic Classification of Low-Mass Pre-Main Sequence Stars in Taurus
We present mid-resolution spectroscopic observations of 35 stars reported to be weak T Tauri stars (WTTS) discovered by ROSAT in the Taurus-Auriga star-forming...
