Star formation in expanding shells
S. Ehlerova, J. Palous
We discuss the induced star formation in dense walls of expanding shells. The fragmentation process is studied using the linear perturbation theory. The influence of the energy inp…

Gamma Ray Bursts versus OB Associations: do they trigger star formation?
Yu. N. Efremov, S. Ehlerova, J. Palous
We discuss differences in shapes, expansion velocities and fragmentation times of structures created by an energy deposition from a single Gamma Ray Burst (GRB) or an OB associatio…

Fragmentation of Expanding Shells in Spiral and Irregular Galaxies
S. Ehlerova, J. Palous, Ch. Theis +1
Conditions for the fragmentation of expanding shells due to gravitational instability are discussed. The self-similar analytical solution is compared with the results of 3-dimensio…
