The Role of the Random Magnetic Fields in the ISM: HVCs Numerical Simulations
A. Santillan, J. Kim, F. J. Sanchez-Salcedo +2
We know that the galactic magnetic field possesses a random component in addition to the mean uniform component, with comparable strength of the two components. This random compone…
On the origin of the neutral hydrogen supershells: the ionized progenitors and the limitations of the multiple supernovae hypothesis
Sergiy Silich, Federico Elias, José Franco
Here we address the question whether the ionized shells associated with giant HII regions can be progenitors of the larger HI shell-like objects found in the Milky Way and other sp…
Exploring cloudy gas accretion as a source of interstellar turbulence in the outskirts of disks
A. Santillan, F. J. Sanchez-Salcedo, J. Franco
High--resolution 2D--MHD numerical simulations have been carried out to investigate the effects of continuing infall of clumpy gas in extended HI galactic disks. Given a certain ac…
Magnetic-Driven Winds from Post-AGB Stars: Solutions for High Speed Winds and Extreme Collimation
Guillermo Garcia-Segura, Jose Alberto Lopez, Jose Franco
This paper explores the effects of post-AGB winds driven solely by magnetic pressure from the stellar surface. It is found that winds can reach high speeds under this assumption, a…
Ultracompact HII Regions
Stan Kurtz, Jose Franco
We review some recent observational results on the properties of ultracompact HII regions, in particular the presence of extended continuum emission surrounding ultracompact source…
Late AGB Magnetic Cycles: MHD Solutions for the HST PN Rings
Guillermo Garcia-Segura, Jose Alberto Lopez, Jose Franco
The Hubble Space Telescope has revealed the existence of multiple, regularly spaced, and faint concentric shells around some planetary nebulae. Here we present 2(1/2)D magnetohydro…
