Torques on low-mass bodies in retrograde orbit in gaseous disks
F. J. Sanchez-Salcedo, R. O. Chametla, A. Santillan
We evaluate the torque acting on a gravitational perturber on a retrograde circular orbit in the midplane of a gaseous disk. We assume that the mass of this satellite is so low it…
Magnetic fields: Impact on the rotation curve of the Galaxy
F. J. Sanchez-Salcedo, A. Santillan
We quantify the effects of magnetic fields, cosmic rays and gas pressure on the rotational velocity of HI gas in the Milky Way, at galactic distances between Rsun and 2Rsun. The ma…
Interaction of HVCs with the Outskirts of Galactic Disks: Turbulence
A. Santillan, F. J. Sanchez-Salcedo, J. Kim +2
There exist many physical processes that may contribute to the driving of turbulence in galactic disks. Some of them could drive turbulence even in the absence of star formation. F…
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…
MHD Remote Numerical Simulations: Evolution of Coronal Mass Ejections
L. Hernandez-Cervantes, A. Santillan, A. R. Gonzalez-Ponce
Coronal mass ejections (CMEs) are solar eruptions into interplanetary space of as much as a few billion tons of plasma, with embedded magnetic fields from the Sun's corona. These p…
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…
