Star formation proceeds in our Galaxy in a way that is not so
easily understood. Giant molecular clouds (GMCs) outweigh the most
massive star clusters by orders of magnitude - star formation is
inefficient. The mass spectrum of young stars - the IMF...
Though the solar wind is characterized by spatial and temporal
variability across a wide range of scales, long-term averages of
in-situ measurements have revealed clear radial trends: changes in
average values of basic plasma parameters (e.g...
The Bahcall Lunch follows the astrophysics colloquium lecture.
Registration is required by 4pm the previous Thursday so a meal can
be provided. Email Amanda at cenker@ias.edu
with questions.
Supernovae, tidal disruption events and merging neutron stars
can provide a wealth of physical insights from nuclear physics to
cosmology; they can teach us about the creation of the elements,
the formation of compact objects, accretion processes...
A majority of black hole-neutron star mergers are expected to
leave little or no tidally disrupted remnant material. Magnetic
field of the neutron star will transition onto the black hole while
leaving a clean magnetosphere during and after the...
Turbulence is arguably one of the most critical physical
processes in galactic disks, playing a key role in the regulation
of different phenomena such as star formation, outflows, and
gravitational instabilities. High-redshift galactic disks,
in...
Abstract: Pulsar timing array experiments
around the world have recently published the first evidence of
nanohertz gravitational waves in the form of a stochastic
gravitational wave background. This discovery opens another window
on the...
In this talk I will do three things. First, I will outline the
conditions under which the interaction rate
of inelastic processes with a system consisting
of N targets scales as N^2. Second, I will present computations of
interaction rates for...
Some small ( 1.6 R⊕) exoplanets have much higher densities than
expected from stellar abundances of planet-forming elements. There
are two theories - metal-rich formation hypothesis and naked core
hypothesis - that explain how formation and...
