Carbon stars as standard candles: II. The median J magnitude as a distance indicator
Javiera Parada, Jeremy Heyl, Harvey Richer +2
We introduce a new distance determination method using carbon-rich asymptotic giant branch stars (CS) as standard candles and the Large and Small Magellanic Clouds (LMC and SMC) as…
Carbon stars as standard candles: I. The luminosity function of carbon stars in the Magellanic Clouds
Paul Ripoche, Jeremy Heyl, Javiera Parada +1
Our goal in this paper is to derive a carbon-star luminosity function that will eventually be used to determine distances to galaxies at - Mpc and hence yield a value of th…
Progress toward optimizing energy and arrival-time resolution with a transition-edge sensor from simulations of X-ray-photon events
Paul Ripoche, Jeremy Heyl
Superconducting transition-edge sensors (TESs) carried by X-ray telescopes are powerful tools for the study of neutron stars and black holes. Several methods, such as optimal filte…
QED effects are negligible for neutron-star spin-down
Paul Ripoche, Jeremy Heyl
The energy loss of a rotationally powered pulsar is primarily carried away as electromagnetic radiation and a particle wind. Considering that the magnetic field strength of pulsars…
Exploring the physics of neutron stars with high-resolution, high-throughput X-ray spectroscopy
Jeremy Heyl, Ilaria Caiazzo, Samar Safi-Harb +21
The advent of moderately high-resolution X-ray spectroscopy with Chandra and XMM promised to usher in a new age in the study of neutron stars: we thought we would study neutron sta…
Testing general relativity with accretion onto compact objects
Ilaria Caiazzo, Jeremy Heyl, Adam R. Ingram +21
The X-ray emission of neutron stars and black holes presents a rich phenomenology that can lead us to a better understanding of their nature and to address more general physics que…
