Description
The galaxy group Klemola 13 is composed of at least seven independent
members including the starburst galaxy Tol 9. Our analysis using
optical/NIR and Ha imaging together with optical spectroscopy suggests
that it is interacting with some members of the group. We propose H I
observations of Klemola 13 in order to map the distribution and
kinematics of the atomic gas throughout the galaxies and look for
features that reveal interaction processes. We will estimate the H I and
the total dynamical mass of the galaxy members and the group. Radio
continuum maps will be used to derive an extinction-free star formation
rate. Comparison with Ha flux enable us to estimate the thermal and
non-thermal contributions of the radio emission. The Ha emission
observed in Tol 9 and its kinematics suggest the presence of an outflow
of ionized gas. Therefore, the non-thermal radio continuum flux will be
used to estimate the available energy in supernovae and examine whether
this would be adequate to drive the Ha outflow. Finally, we will combine
all the available multiwavelength data to describe the star-formation
history, the dynamical and chemical evolution of this group of galaxies.
