Detecting primordial stars (2007)
Scannapieco, Evan, Ferrara, Andrea, Heger, Alexander, Madau, Piero, Schneider, Raffaella, Woosley, Stan
We study the detectability of primordial metal-free stars. Cosmological enrichment is a local process that takes place over an extended redshift range. While the duration of this transition depends...
New approaches for modeling type Ia supernovae (2007)
Zingale, Michael, Almgren, Ann S., Bell, John B., Day, Marcus S., Rendleman, Charles A., Woosley, Stan
Type Ia supernovae (SNe Ia) are the largest thermonuclear explosions in the Universe. Their light output can be seen across great stances and has led to the discovery that the expansion rate of the...
The Supernova Gamma-Ray Burst Connection (2006)
Woosley, Stan, Heger, Alexander
The chief distinction between ordinary supernovae and long-soft gamma-ray bursts (GRBs) is the degree of differential rotation in the inner several solar masses when a massive star dies, and GRBs are...
Detecting Primordial Stars (2005)
Scannapieco, Evan, Ferrara, Andrea, Heger, Alexander, Madau, Piero, Schneider, Raffaella, Woosley, Stan
We study the detectability of primordial metal-free stars. Cosmological enrichment is a local process that takes place over an extended redshift range. While the duration of this transition depends...
The Progenitor Stars of Gamma-Ray Bursts (2005)
Woosley, Stan, Heger, Alexander
Those massive stars that, during their deaths, give rise to gamma-ray bursts (GRBs) must be endowed with an unusually large amount of angular momentum in their inner regions, one to two orders of...
The Detectability of Pair-Production Supernovae at z < 6 (2005)
Scannapieco, Evan, Madau, Piero, Woosley, Stan, Heger, Alexander, Ferrara, Andrea
Nonrotating, zero metallicity stars with initial masses 140 < M < 260 solar masses are expected to end their lives as pair-production supernovae (PPSNe), in which an electron-positron pair-production...
GRB 020410: A Gamma-ray burst afterglow discovered by its supernova light (2004)
Levan, Andrew, Nugent, Peter, Fruchter, Andrew, Burud, Ingunn, Branch, David, Rhoads, James, ...
We present the discovery and monitoring of the optical transient (OT) associated with GRB 020410. The fading OT was found by Hubble Space Telescope (HST) observations taken 28 and 65 days after burst...
Evolution and explosion of very massive primordial stars (2002)
Heger, Alexander, Woosley, Stan, Baraffe, Isabelle, Abel, Tom
New Results on Nucleosynthesis in Massive Stars; Nuclear Data Needs for (2001)
Nucleosynthesis Robert Hoffman, Robert Hoffman, Thomas Rauscher, Alex Heger, Stan Woosley
Introduction Second only in scientific interest to the origin of the universe itself is the origin of the chemical elements therein. The near term goal of nuclear origins, or nucleosynthesis, seeks...
