Herbig-Haro objects were discovered 50 years ago, and during this
half century they have developed from being mysterious small
nebulae to be coming an important phenomenon in star formation.
Indeed, HH flows are now recognized not only as fascinating
astrophysical laboratories involving shock physics and chemistry,
hydrodynamics and radiation processes, but it has gradually been
realized that HH flows hold essential clues to the birth and early
evolution of low mass stars. IAU Symposium No. 182 on Herbig-Haro
Flows and the Birth of Low Mass Stars were held from January 20 to
24, 1997 in Chamonix in the french alps. A total of 178 researchers
from 26 countries met to discuss our present level of understanding
of Herbig-Haro flows and their relation to disk accretion events
and T Tauri winds and other outflow phenomena like molecular
outflows, embedded molecular hydrogen flows and radio jets. The
present book contains the manuscripts from the oral contributions
of the symposium. The poster papers were printed in a separate
volume Low Mass Star Formation - from Infall to Outflow, edited by
Fabien Malbet and Alain Castets, which was distributed at the
beginning of the meeting. Together these two books document the
vigorous state and the scientific appeal which research into
Herbig-Haro flows and related issues in star formation enjoys
today, observationally as well as theoretically."
As a young researcher in astronomy whose advisor has just told you
to write a paper to present your first results, you are thrilled
but also worried, because you realize that the quality of your
publication is crucial for your career. This Guide to Effective
Publishing in Astronomy is for you. It gives you the practical
information for publishing your article in one of the major
research journals in the field of astronomy and addresses all
aspects of the process. It also explains how a good scientific
paper should be written and gives you both an overview of the
refereeing process and recommendations on how to avoid common
mistakes when writing in English. You will also find: detailed
information on the peer-review validation system, a brief history
of the major journals in the field of astronomy, their requirements
and the ways they are run, information on services offered by
astronomy libraries and databases such as the Strasbourg CDS. Along
the way you will find lots of useful information for your career as
a researcher.
In addition to being fascinating astrophysical laboratories in
their own right, Herbig-Haro flows have in recent years emerged as
key phenomena in our attempts to understand the complex and violent
processes that govern the birth of low mass stars. This work
provides an overview of the major advances which the study of
Herbig-Haro jets has enjoyed since 1995. On the observational side,
Hubble Space Telescope images have revealed the intricate details
of the shock structures in these supersonic flows, millimetre
interferometry and infrared imaging can now probe the detailed
structure of the molecular component of deeply embedded jets, and
sub-millimetre and radio continuum maps now enable us to study the
near environment of the optically invisible driving sources of
jets. On the theoretical side, detailed numerical and analytical
magnetohydrodynamic models have reached a level of sophistication
that allows realistic comparison with observations and insights
into the jet formation mechanisms. Similarly detailed observational
and theoretical studies of the disks and winds of T Tauri stars are
now gradually being linked to the Herbig-Haro flows, providing a
first glimpse of how stars can be born by both accreting and
ejecting infalling material.
