FOREWORD
The objective of this workshop was to put together observational and
theoretical works on outflows from different kinds of astrophysical
objects, occurring on different scales and at various evolutionary
phases, and to discuss the impact of observations from future space
missions. For the stars, we thought to follow throughout the evolution
the relevance (rates and dynamical rrodes) of the mass loss phenomenon,
e. g. to explain how and when massive stars loose most of their init ial
mass to end up with typical WD masses. The observations of the solar
wind were included for being a unique case where the origin and
propagation of the outflow can be resolved. We thought that the
comparison with similar phenomena occurring in galactic outflows would
be fruitful, as demonstrated by recent works on galactic winds and jets.
The interest of having this workshop in Torino came because there are
groups in this area, at the Astronomical Observatory and at the
Institute of Physics of the University, involved in the theoretical and
observational studies of outflows from astrophysical objects.
The members of the Scientific Organizing Conmi ttee were: V. Castellani,
C.Cesarski, P.Conti, A.Ferrari, A.Gabriel, M.Grewing, Y.Kondo, H.Lamers,
V. Manno, M. Rees and R. Schilizzi. The Local Organizing Conmi ttee was:
L. Bianchi, G. Massone and E. Antonucci.
During the workshop the following topics were treated: the solar wind,
the mass loss from cool stars and from hot stars (m. s. stars,
supergiants and evolved stars like Planetary Nebulae nuclei), the
formation of Planetary Nebulae, the mass flows in interacting binary
systems, and the cases of collimated outflows: young stellar objects
and galactic nuclei. Recent results on these topics were presented in
16 invited reviews and 61 contributed and poster papers. The future
space projects of the European Space Agency which could provide relevant
observations for the study of astrophysical outflows were illustrated in
7 invited presentations.
This workshop has been realized thanks to the financial support of:
Consiglio Nazionale delle Ricerche, European Space Agency, Cassa di
Risparmio di Torino, Citta' di Torino, Provincia di Torino, Regione
Piemonte, Unione Industriale and A. M. M. A. During the workshop, the help
of several members of the staff of the Astronomical Observatory: M.
Marini, G. Chiumiento, E. deZanet, M. Lattanzi, R. Manzi, F. Racioppi and
M.Sarasso has been extrerrely valuable.
