The isotopic fractionation, i.e., the chemical process by which less abundant stable isotopes of elements are transferred to molecules, is still not well-understood. ... The sensitivity of sub-millimeter (ALMA, NOEMA, APEX, IRAM-30m) and IR (Spitzer, Herschel) observational facilities, and new chemical models are starting to shed light also on the fractionation of elements less abundant than H, with special attention to the possible link between this process and the evolution of the host environment. ...

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

In ancient times the solar system was thought to be the whole Universe, so the study of planetary motions was cosmology. ... The planets other than the Moon and Sun generally move West to East through the stars, but occasionally stop and move in the opposite direction ( retrograde motion). In order to explain the retrograde motion of the planets, the geocentric model of the Solar System shown above puts the planets on small circles called epicycles . ...

System of astrometric databases of Pulkovo observatory. ... The purpose of these observations is the determination of precise coordinates of Solar system bodies, which is necessary for development and improvement of motion theories, and for studying the evolution of the Solar system. ... Accuracy of photographical observations is about 0.2-0.3 arcsec for equatorial coordinates and 0.1-0.3 for relative coordinates of planetary satellites, depending on object and observational conditions. ...

Next: X--ray Activity and PMS stars . ... This has made the need to study the evolution of the rotation periods of stars, and hence the angular momentum, very clear. ... In the case of low mass pre--main sequence (PMS) stars, we seek to learn whether disks alone determine the angular momentum distribution when stars arrive on the main sequence. ... If one assumes that angular momentum is conserved from the natal cloud, then rotation periods exceeding breakup velocity are implied for PMS stars. ...
