Neutron Star Kicks and Supernova Asymmetry
Dong Lai
Observations over the last decade have shown that neutron stars receive a large kick velocity (of order a hundred to a thousand km/s) at birth. The physical origin of the kicks and…
Radiative Transfer Modeling of Passive Circumstellar Disks: Application to HR4796A
T. Currie, D. Semenov, Th. Henning +2
We present a radiative transfer model which computes the spectral energy distribution of a passive, irradiated, circumstellar disk, assuming the grains are in radiative equilibrium…
Pulsar Parallaxes at 5 GHz with the Very Long Baseline Array
S. Chatterjee, J. M. Cordes, W. H. T. Vlemmings +3
We present the first pulsar parallaxes measured with phase-referenced pulsar VLBI observations at 5 GHz. Due to the steep spectra of pulsars, previous astrometric measurements have…
NLTE Spectral Analysis of Central Stars of PNe Interacting with the ISM
T. Rauch, F. Kerber, E. Furlan +1
The analysis of Planetary Nebulae (PNe) provides a tool to investigate the properties of their exciting central stars (CSPN) at the moment of the PN ejection as well as on the prop…
Smashing the Guitar: An Evolving Neutron Star Bow Shock
S. Chatterjee, J. M. Cordes
The Guitar nebula is a spectacular example of an H-alpha bow shock nebula produced by the interaction of a neutron star with its environment. The radio pulsar B2224+65 is traveling…
Inner Halo Shapes of Dwarf Galaxies: Resolving the Cusp/Core Problem
K. Spekkens, R. Giovanelli
We derive inner dark matter halo density profile slopes for a sample of 200 dwarf galaxies by inverting rotation curves obtained from high-quality, long-slit optical spectra. Using…
