Calcium/Sodium in the Milky Way . ... We map out calcium II sodium I absorption - corresponding to Fraunhofer H, K D lines - induced by both the interstellar medium and the circumgalactic medium of the Milky Way. ... We show that the abundance of sodium with respect to neutral hydrogen stays roughly constant in different environments, while that of calcium decreases with column density. ... Here we show the maps of calcium and sodium in the Milky Way based on the obtained data. ... Projects | ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

... Contact A Problem of an estimation of accuracy of the asteroid CCD observations . The Minor Planet Center supported by the Interntional Astronomical Union is the main office for keeping observational data of the small Solar System bodies and their investigations. ... At Pulkovo Observatory we are estimating an accuracy of the CCD asteroid observations obtained by amateurs and professional astronomers all over the World using the MPC database. ...

АНОНС НАУЧНЫХ КОНФЕРЕНЦИЙ 1998-99 гг. ... An AAS Electronic Announcement Dear Colleague: NASA has approved development of a Wide Field Camera 3 (WFC3) for installation in the HST on the 2002 Servicing Mission. A Scientific Oversight Committee (SOC) is being established to ensure that the broad interests of the scientific community are represented in the development of WFC3. The primary task of the SOC will be to advise the HST Project and STScI in all areas of scientific performance of WFC3. ...

When Apache starts, it connects to some port and address on the local machine and waits for incoming requests. By default, it listens to all addresses on the machine, and to the port as specified by the Port directive in the server configuration. ... There are two directives used to restrict or specify which addresses and ports Apache listens to. ... Listen can be used to make a single Apache server listen to more than one address and/or port. ... Syntax: Listen [ port | IP-address:port ] . ...

... Seminar archive . ... Type Ia Supernovae (SNe Ia) have an important role to measure a distance to an anonymous galaxy because they have a good correlation of the decline rates of the light curves with the absolute luminosity. ... First, super-Chandrasekhar SNe which have extremely high luminosity, slow decline rate of the light curves, slow expansion velocity and strong carbon features. ... As another example of diversity of SNe Ia, I would like also to introduce Type Iax SNe. ... All seminars: . ...
