Numerical Simulation of the Viscous-like Flow in and Around the Plasma Tail of a Comet
M. Reyes-Ruiz, H. Perez-de-Tejada, H. Aceves +1
We model the interaction of the solar wind with the plasma tail of a comet by means of numerical simulations, taking into account the effects of viscous-like forces.A 2D hydrodynam…
Multiple and Precessing Collimated Outflows in the Planetary Nebula IC 4634
M. A. Guerrero, L. F. Miranda, A. Riera +6
With its remarkable double-S shape, IC 4634 is an archetype of point-symmetric planetary nebulae (PN). In this paper, we present a detailed study of this PN using archival HST WFPC…
NGC 2401: A template of the Norma-Cygnus Arm's young population in the Third Galactic Quadrant
G. Baume, A. Moitinho, R. Vazquez +3
Based on a deep optical CCD (UBV(RI)_C) photometric survey and on the Two-Micron All-Sky-Survey (2MASS) data we derived the main parameters of the open cluster NGC 2401. We found t…
A photometric study of the old open clusters Berkeley 73, Berkeley 75 and Berkeley 25
G. Carraro, D. Geisler, A. Moitinho +2
CCD BVI photometry of the faint open clusters Berkeley~73, Berkeley~75 and Berkeley~25 are presented. The two latter are previously unstudied clusters to our knowledge. While Berke…
Unveiling the structure of the planetary nebula M 2-48: Kinematics and physical conditions
L. Lopez-Martin, J. A. Lopez, C. Esteban +6
The kinematics and physical conditions of the bipolar planetary nebula M 2-48 are analysed from high and low dispersion long-slit spectra. Previous CCD narrow-band optical observat…
Morphological and kinematic signatures of a binary central star in the planetary nebula Hu 2-1
Luis F. Miranda, Jose M. Torrelles, Martin A. Guerrero +2
We present narrow-band optical images, VLA-A 3.6 cm continuum and H92alpha emission line data and high resolution long-slit [N II] spectra of Hu 2-1. The formation of Hu 2-1 appear…
