Bulge Formation
The currently discussed theories of bulge formation are reviewed, including the pri-mordial scenario, where bulges form rapidly and then accrete disks, the secular scenario, where bulges are formed by dynamical evolution of disks through bars and galaxy interactions , and some combinations of both, where formation of bulges and disks are more continuous and interleaved. The various scenarios ma...
متن کاملPlanetesimal Formation through Gravitational Instability
Introduction. Two prevailing processes of planetesimal formation are proposed. The first is the gravitational instability of a dust layer (e.g., Safronov 1969, Hayashi 1972, Goldreich and Ward 1973). The second is the growth through the mutual sticking of dust particles in a turbulent nebula (Weidenschilling and Cuzzi 1993, Stepinski and Valageas 1997). We consider the first one in this study. ...
متن کاملGravitational instability and star formation in disc galaxies
We present a general star formation law in which the star formation rate depends upon the ef®ciency a and the time-scale t of star formation, and the gas component jg of the surface mass density. The current nominal Schmidt exponent nS for our model is 2 < nS < 3. Based on a gravitational instability parameter QA and another dimensionless parameter fP P=Gj 2 c , where P pressure and jc ...
متن کاملThe Disc Origin of the Milky Way Bulge
The Galactic bulge, that is the prominent out-of-plane over-density present in the inner few kiloparsecs of the Galaxy, is a complex structure, as the morphology, kinematics, chemistry, and ages of its stars indicate. To understand the nature of its main components—those at [Fe/H] −1 dex—it is necessary to make an inventory of the stellar populations of the Galactic disc(s), and of their border...
متن کاملChiari Formation: Atlantoaxial Instability is the Cause
The entity of Chiari formation was described by Hans Chiari in 1891 [1,2]. Since then the subject has been evaluated elaborately by a number of authors. However, it may only be correct to state that confusion in the understanding of pathogenesis and the nature of anomaly, significance of associated abnormal soft tissue and bone anomalies and more importa...
