Context. HH 30 is a well-known Pre-Main-Sequence star in Taurus. HST observations have revealed a flared, edge-on disk driving a highly-collimated optical jet, making this object a case study for the disk-jet-outflow paradigm. Aims. We searched for a molecular outflow, and attempted to better constrain the star and disk parameters. Methods. We obtained high angular resolution (∼ 1′′) observatio...

We present a high–resolution study of NGC 2264 IRS1 in CS 2→1 and in the 3-mm continuum using the IRAM Plateau de Bure Interferometer. We complement these radio data with images taken at 2.2 µm, 4.6 µm, and 11.9 µm. The combined information allow a new interpretation of the closest environment of NGC 2264 IRS1. No disk around the B–type star IRS1 was found. IRS1 and its low–mass companions are ...

Precise-Doppler experiments suggest that a massive (m sin i = 0.86MJ) planet orbits at semimajor axis a = 3.4 AU around ǫ Eridani, a nearby star with a massive debris disk. The dynamical perturbations from such a planet would mold the distribution of dust around this star. We numerically integrated the orbits of dust grains in this system to predict the central dust cloud structure. For a suppl...

We report the detection of 6 active galactic nuclei, and also the marginal detection of the galactic center radio source SGRA*, in 215GHz VLBI observations between the IRAM 30m telescope on Pico Veleta and one 15m antenna of the IRAM Plateau de Bure interferometer (∼ 0.3mas fringe spacing). In this (second) 1.4mm VLBI-experiment we find source dependent ratios between the total and correlated f...

We present the results of a CO survey of gravitationally lensed quasars, conducted with the Plateau de Bure Interferometer over the last three years. Among the 18 objects surveyed, one was detected in CO line emission, while six were detected in the continuum at 3mm and three in the continuum at 1mm. The low CO detection rate may at least in part be due to uncertainties in the redshifts derived...

We report on the detection of the CO(4−3) line with the IRAM Plateau de Bure Interferometer in two z > 3 radio galaxies, doubling the number of successful detections in such objects. A comparison of the CO and Lyα velocity profiles indicates that in at least half of the cases, the CO is coincident in velocity with associated HI absorption seen against the Lyα emission. This strongly suggests th...

This contribution presents a short overview about the investigation of the molecular gas content of nearby galaxies using the Plateau de Bure Interferometer. I try to give a rather complete list of recent references, and explicit descriptions are given for objects under study at RAI Bonn. They comprise very different types of galaxies such as Haro 2, Mrk 297, M82, NGC2146, M31 and NGC4258. All ...
