`` Recent Results on the Primordial Helium Abundance
and Big Bang Nucleosynthesis Consistency''
DR. DIMITAR SASSELOV
Center for Astrophysics

Abstract:

Current estimates of the primordial Helium-4 abundance may
suffer from systematic uncertainties (in the direction of being
underestimated). Combined with recent results on D and Li, the value of
Omega in baryons from Big Bang Nucleosynthesis (BBN) is reconsidered
and the consistency of BBN examined.  At a less significant level, the
Helium-4 abundance also plays a role in constraining the lower limit on
the age of the Universe (via globular cluster ages).

``Relativistic Jet Sources in Our Galaxy''     

DR. ROBERT J. HJELLMING  

National Radio Astronomy Observatory
Socorro, NM     


Abstract:     


The recent discovery of highly relativistic (v = 0.92c) radio jets
from GRS1915+105 and GRO J1655-40 indicates that the study of this
class of objects may be the best way to understand the production
of relativistic jets from compact objects, many or all of which are
black holes.  This talk will discuss the known radio properties of
SS433, Cyg X-3, and GRS1915+105 as background for the work on the high
resolution image sequences and X-ray to radio correlations, and different
radio-XR states, seen for the black hole binary GRO J1655-40.
GRO J1719-24 will be discussed because of its similar XR-radio
correlations. The probability that A0620-00, GS2000+35, V404 Cyg,
Nova Muscae 1991, and similar X-ray transients are the same type of
relativistic jet object will be assessed.  


Tea will be served at 3:30 p.m.
