Radioactive nuclei in the early Solar System: analysis of the 15 isotopes produced by core-collapse supernovae
Thomas V. Lawson, Marco Pignatari, Richard J. Stancliffe +5
Short-lived radioactive isotopes (SLRs) with half-lives between 0.1 to 100 Myr can be used to probe the origin of the Solar System. In this work, we examine the core-collapse super…
BSE versus StarTrack: implementations of new wind, remnant-formation, and natal-kick schemes in NBODY7 and their astrophysical consequences
Sambaran Banerjee, Krzysztof Belczynski, Christopher L. Fryer +4
The masses of stellar-remnant black holes (BH), as a result of their formation via massive single- and binary-stellar evolution, is of high interest in this era of gravitational-wa…
Radiation Transport Through Super-Eddington Stellar Winds
Joyce A. Guzik, Chris Fryer, Todd J. Urbatsch +1
We present results of simulations to assess the feasibility of modeling outflows from massive stars using the Los Alamos 3-D radiation hydrodynamics code Cassio developed for inert…
The role of dredge-up in double white dwarf mergers
Jan E. Staff, Brandon Wiggins, Dominic Marcello +6
We present the results of an investigation of the dredge-up and mixing during the merger of two white dwarfs with different chemical compositions by conducting hydrodynamic simulat…
NuGrid Stellar Data Set. II. Stellar Yields from H to Bi for Stellar Models with Mzams = 1 to 25Msun and Z = 0.0001 to 0.02
C. Ritter, F. Herwig, S. Jones +3
We provide here a significant extension of the NuGrid Set 1 models in mass coverage and toward lower metallicity, adopting the same physics assumptions. The combined data set now i…
Microlensing constraints on the mass of single stars from HST astrometric measurements
Noé Kains, A. Calamida, K. C. Sahu +13
We report on the first results from a large-scale observing campaign aiming to use astrometric microlensing to detect and place limits on the mass of single objects, including stel…
