Planets in Stellar Clusters Extensive Search. V. Search for planets and identification of 18 new variable stars in the old open cluster NGC 188
B. J. Mochejska, K. Z. Stanek, D. D. Sasselov +7
We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. In this paper we present the resul…
Classical Nucleation Theory of the One-Component Plasma
Randall L. Cooper, Lars Bildsten
We investigate the crystallization rate of a one-component plasma (OCP) in the context of classical nucleation theory. From our derivation of the free energy of an arbitrary distri…
Damping of Type I X-ray Burst Oscillations by Convection
Randall L. Cooper
I construct a simple model of the convective burning layer during a type I X-ray burst to investigate the effects convection has on the stability of the layer to nonradial oscillat…
Generation of Type I X-ray Burst Oscillations by Unstable Surface Modes
Ramesh Narayan, Randall L. Cooper
The Rossi X-ray Timing Explorer has detected nearly coherent oscillations in the tails of type I X-ray bursts from 17 low-mass X-ray binaries. The oscillations are thought to be ge…
Experimental measurements of the O15(alpha,gamma)Ne19 reaction rate and the stability of thermonuclear burning on accreting neutron stars
Jacob Lund Fisker, Wanpeng Tan, Joachim Goerres +2
Neutron stars in close binary star systems often accrete matter from their companion stars. Thermonuclear ignition of the accreted material in the atmosphere of the neutron star le…
Hydrogen-Triggered Type I X-ray Bursts in a Two-Zone Model
Randall L. Cooper, Ramesh Narayan
We use the two-zone model of Cooper & Narayan to study the onset and time evolution of hydrogen-triggered type I X-ray bursts on accreting neutron stars. At the lowest accretion ra…
The Latitude of Type I X-Ray Burst Ignition on Rapidly Rotating Neutron Stars
Randall L. Cooper, Ramesh Narayan
We investigate the latitude at which type I X-ray bursts are ignited on rapidly rotating accreting neutron stars. We find that, for a wide range of accretion rates, ignition occurs…
On the Physics of Type I X-ray Bursts on Accreting Neutron Stars at High Accretion Rates
Randall L. Cooper, Ramesh Narayan
We investigate the effect of the hot CNO cycle breakout reaction 15O(alpha,gamma)19Ne on the occurrence of type I X-ray bursts on accreting neutron stars. For f_rp <~ 0.1, where f_…
A Two-Zone Model for Type I X-ray Bursts on Accreting Neutron Stars
Randall L. Cooper, Ramesh Narayan
We construct a two-zone model to describe H and He burning on the surface of an accreting neutron star and use it to study the triggering of type I X-ray bursts. Although highly si…
Planets in Stellar Clusters Extensive Search. IV. A detection of a possible transiting planet candidate in the open cluster NGC 2158
B. J. Mochejska, K. Z. Stanek, D. D. Sasselov +9
We have undertaken a long-term project, Planets in Stellar Clusters Extensive Search (PISCES), to search for transiting planets in open clusters. In this paper we present the resul…
The Rates of type I X-ray Bursts from Transients Observed with RXTE: Evidence for Black Hole Event Horizons
Ronald A. Remillard, Dacheng Lin, Randall L. Cooper +1
We measure the rates of type I X-ray bursts, as a function of the bolometric luminosity, from a likely complete sample of 37 non-pulsing transients (1996-2004). Our goals are to te…
On the Production and Survival of Carbon Fuel for Superbursts on Accreting Neutron Stars: Implications for Mass Donor Evolution
Randall L. Cooper, Banibrata Mukhopadhyay, Danny Steeghs +1
(abridged) We have investigated the physical conditions under which accreting neutron stars can both produce and preserve sufficient quantities of carbon fuel to trigger superburst…
Theoretical Models of Superbursts on Accreting Neutron Stars
Randall L. Cooper, Ramesh Narayan
We carry out a general-relativistic global linear stability analysis of the amassed carbon fuel on the surface of an accreting neutron star to determine the conditions under which…
Hot Interstellar Gas and Stellar Energy Feedback in the Antennae Galaxies
J. M. Metz, R. L. Cooper, M. A. Guerrero +3
We have analyzed Chandra archival observations of the Antennae galaxies to study the distribution and physical properties of its hot interstellar gas. Eleven distinct diffuse X-ray…
Energy Crisis in the Superbubble DEM L 192 (N 51D)
R. L. Cooper, M. A. Guerrero, Y. -H. Chu +2
Superbubbles surrounding OB associations provide ideal laboratories to study the stellar energy feedback problem because the stellar energy input can be estimated from the observed…
