Long Baseline Interferometric Observations of Cepheids
We present observations of the galactic cepheids η Aql and ζ Gem. Our observations are able to resolve the diameter changes associated with pulsation. This allows us to determine the distance to the Cepheids independent of photometric observations. We determine a distance to η Aql of 320 ± 32 pc, and a distance to ζ Gem of 362±38 pc. These observations allow us to calibrate surface brightness r...

متن کاملInterferometric CO observations
We present interferometric observations of CO(1–0) emission in the elliptical galaxy NGC759 with an angular resolution of 3 . ′′1×2 . 3 (990×735pc at a distance of 66Mpc). NGC759 contains 2.4 × 10M⊙ of molecular gas. Most of the gas is confined to a small circumnuclear ring with a radius of 650pc with an inclination of 40. The maximum gas surface density in the ring is 750M⊙ pc . Although this ...
متن کاملInterferometric observations of nearby galaxies
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 ...
متن کاملInterferometric Observations of V838 Monocerotis
We have used long-baseline near-IR interferometry to resolve the peculiar eruptive variable V838 Mon and to provide the first direct measurement of its angular size. Assuming a uniform disk model for the emission we derive an apparent angular diameter of 1.83±0.06 milli-arcseconds. For a nominal distance of 8 ± 2 kpc, this implies a linear radius of 1570 ± 400R⊙. However, the data are somewhat ...
