چکیده
The importance of initial conditions to considerations of solar system and stellar formation processes is discussed. Astronomical knowledge relating to regions of current stellar formation in our Galaxy is reviewed. The potential of radio observations of astrophysical H20 masers as a means of probing the regions of current stellar formation at high resolution is discussed. Radio observations of H20 masers (single antenna and interferometric) are presented. A mathematical model of an H20 maser is developed and examined numerically. Comparisons between numerical models and the radio observations are made to obtain estimates of linear dimensions, radial and transverse velocities, temperature, and density. Some implications for understanding stellar formation processes are discussed. Thesis Supervisor: Irwin I. Shapiro Professor of Geophysics and Physics

Relativistic Stellar Models with Quadratic Equation of State
In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...
متن کاملStellar Populations in the Central Galaxies of Fossil Groups
It is inferred from the symmetrical and luminous X-ray emission of fossil groups that they are mature, relaxed galaxy systems. Cosmological simulations and observations focusing on their dark halo and inter-galactic medium properties confirm their early formation. Recent photometric observations suggest that, unlike the majority of non-fossil brightest group galaxies (BGGs), the central early-t...
متن کاملThe Geometry of Karbandi in Persian Architecture; Response to the Challenges of Conventional and Stellar Karbandi
Karbandi is one of the original and ancient arched elements in Persian architecture which is formed based on a network with harmonic geometry and in addition to architectural function, it also has structural behavior. However, there are ambiguities about the geometry of this architectural element that should be addressed with targeted research. One of these ambiguities is to determine how the g...
متن کاملLocal stability criterion for self-gravitating disks in modified gravity
We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a point mass. We investigate the effect of such a Yukawa-like term on the dynamics of self-gravitating disks. More specifically, we investigate the consequences of the presence of this term for the local stability of t...
متن کاملThe effect of variation of stellar dispersion velocities by the galactic latitude in interpreting gravitational microlensing observations
Our galaxy is a spiral galaxy and its stars are mostly in a thin disk and rotate around the galactic center. The vertical component of the dispersion velocity of stars is a function of the galactic latitude and decreases with increasing it. In the galactic Besancon model, this dependence is ignored and they just consider the dependence of dispersion velocity on the stellar age. Becanson model i...
