نویسنده
چکیده
ASTRO-F is the second Japanese space mission for infrared astronomy and is scheduled to be launched into a sun-synchronous polar orbit by the Japanese M-V rocket in February 2004. ASTRO-F has a cooled 67 cm telescope with two focal plane instruments: one is the FarInfrared Surveyor (FIS) and the other is the Infrared Camera (IRC). The main purpose of FIS is to perform the all-sky survey with 4 photometric bands in the wavelength range of 50 200 μm. The advantages of the FIS survey over the IRAS survey are (1) higher spatial resolution (30 at 50110 μm and 50 at 110-200 μm) and (2) better sensitivity by one to two orders of magnitude. The FIS survey will provide the next generation far-infrared survey catalogs, which will be ideal inputs for observations by FIRST. The other instrument, IRC, will make deep imaging and low-resolution spectroscopic observations in the spectral range of 1.8 − 26μm. The IRC will make large-area surveys with its wide field of view (10 × 10), and will be complementary with the FIRST observations at longer wavelengths.

With the advent of optical interferometers that will be coming online in the next decade, radial velocity searches for extra-solar planets will be complemented by high angular resolution astrometric measurements. In this paper, we explore the sensitivity of the astrometric technique, and develop an analytical understanding of the sensitivity in the regime where the orbital period is longer than...

We review the current knowledge and understanding of the interstellar medium of our galaxy. We first present each of the three basic constituents – ordinary matter, cosmic rays, and magnetic fields – of the interstellar medium, laying emphasis on their physical and chemical properties inferred from a broad range of observations. We then position the different interstellar constituents, both wit...

We examine the claim by Oppenheimer et al. (2001) that the local halo density of white dwarfs is an order of magnitude higher than previously thought. As it stands, the observational data support the presence of a kinematically distinct population of halo white dwarfs at the >99% confidence level a. A maximum-likelihood analysis gives a radial velocity dispersion of σ h U =160
