Spring 2003
2/18: Emrah Kalemci will discuss his work
on temporal studies of Black Hole X-ray transients.
Reading is here.
Fall 2002
9/17/2002: Wayne Coburn
will lead a discussion on x-ray absorption
(cyclotron?) features recently
reported in one isolated neutron star
and one AXP. The relevant papers
are:
"Discovery of Absorption Features in the X-Ray Spectrum of an Isolated Neutron Star"
Chandra High-Resolution Spectrum of the Anomalous X-Ray Pulsar 4U 0142+61
"Comment
on ``Discovery of the absorption features in the X-ray spectrum
of
an isolated neutron star''"
Spring 2002
2/12/2002: Jon
Arons & Don Backer will lead a discussion on
"polar cap weather on neutron stars" (from radio
pulsar timing).
Readings: Lyne
& Ashworth, Deshpande
& Rankin. For some theoretical
context, Jon suggests Section VI of Ruderman
& Sutherland
2/19/2002: We will discuss Selfgravity
and QSO disks by Jeremy Goodman; Yuri will help lead.
This paper addresses some of the complex issues associated with how mass
makes
it from galactic scales to the black hole in AGN, focusing on the outer
parts
of the disk where self-gravity and star formation are probably important.
3/11/02: We will discuss
Saturation
of the R-mode Instability by Arras et al. The first
and last sections provide a nice summary of the context and results.
This week
we will meet up at SSL.
4/2/02: Andrew
Westphal is going to lead a discussion of some of his instrument work.
A recommended paper is: ``Evidence against stellar chromospheric origin
of
galactic cosmic rays,'' Westphal, et al., Nature
396, 50 (1998).
We will meet in 501 Campbell.
4/9/02:
We will talk about X-ray Clusters and "Cooling Flows" in the Chandra and
XMM era.
A nice & brief review of some of the issues is McNamara et al. at astro-ph/0012331
(a somewhat longer and somewhat more recent version is McNamara
astro-ph/0202199).
Lunch will be in Campbell.
