Week of April 7-April 13, 1996

The Boston Area Physics Calendar is published weekly during 
the academic year by the Department of Physics and Astronomy 
at Tufts University.  You may send your announcements by 
e-mail (bapc@tuhepa.phy.tufts.edu) or FAX:(617-627-3878).  
We cannot accept announcements by telephone.  Entries should 
reach us no later than 11:00am on the Monday preceding the week

Abstract:
 
Epitaxial synthesis by molecular beam epitaxy provides an important new
route to the exploration of magnetic systems, ferroelectricity, atomic
mobility, irradiation effects, metastable phases, and many other aspects of
materials science.  Examples are given of applications to a variety of
research problems.  Particular emphasis will be placed on examples of
recent research that resolve problems of diffusion in oxide materials and
of irradiation-induced mixing in intermetallic compounds.

``Extreme Ultraviolet Spectroscopy: What's Hot 
about Cool Stars ?''
DR. ANDREA DUPREE
Harvard-Smithsonian Center for Astrophysics 
 
Abstract:
 
The Sun's atmosphere has long been taken as the
archetypical stellar corona; however, surprisingly different
coronal structures are revealed by  spectra of cool
stars recently obtained with the Extreme Ultraviolet Explorer satellite.
Spectroscopy in the extreme ultraviolet (EUV) wavelength
region (80A-700A) offers a unique technique to measure
physical conditions in cosmic plasmas with temperatures
up to 20 million degrees and densities higher than
$10^{13} over/cm^{3}$.  For the first time, we have indications from
spectral diagnostics for small, hot, high density regions produced
in rapidly rotating stellar atmospheres with some systems
exhibiting phenomena that have no solar counterpart.  Stellar coronae are
more complex than previously thought with pressures up to 5 orders
of magnitude higher than solar active regions.  Puzzling observations
of abundance variations are also suggested by EUV and X-ray
spectroscopy with EUVE and ASCA.  Energetic flaring events occur in some
objects.  The new EUV results have consequences
for energy balance and dynamics of coronae and cosmic plasmas.
