... It was found that the Sun lies 9?2 pc above the plane of hte Galactic disk in the direction of North Galactic pole and that F0-F9 stars contribute 0.0035 M /pc 3 to the density of the Galactic disk. ... We used this method to determine the scale height of the subsystem of F stars of the Galactic disk, Z 0 =160?10 pc. ... It is suggested that scale height of the metal-poor stars subsystem is due to the infall of the metall-poor intergalactic gas onto the disk. ...

... Programme . ... Presenter: Nadine Neumayer (ESO) . Abstract: I will present the determination of the mass of the supermassive black hole of Centaurus A using high-resolution integral-field observations of both the gas and the stellar kinematics. ... The black hole mass measurements of both tracers, gas and stars, are in excellent agreement and provide one of the cleanest gas versus stars comparisons of a BH mass determination. ...

... We present 7mm observations of the dusty disk surrounding the 10 Myr old 1.5 Msun pre-main-sequence star CQ Tauri obtained at the Very Large Array with 0.8 arcsecond resolution and 0.1 mJy rms sensitivity. ... We find that the disk radius is constrained to the range 100 to 300 AU, depending on the steepness of the disk surface density distribution. The power law index of the dust opacity coefficient, beta, is constrained to be 0.5 to 0.7. ...
