Nuclear Burning in Collapsar Accretion Disks
Yossef Zenati, Daniel M. Siegel, Brian D. Metzger +1
The core collapse of massive, rapidly-rotating stars are thought to be the progenitors of long-duration gamma-ray bursts (GRB) and their associated hyper-energetic supernovae (SNe)…
LRP2020: The cosmic origin and evolution of the elements
Rodrigo Fernández, Falk Herwig, Samar Safi-Harb +16
The origin of many elements of the periodic table remains an unsolved problem. While many nucleosynthetic channels are broadly understood, significant uncertainties remain regardin…
r-Process Nucleosynthesis: Connecting Rare-Isotope Beam Facilities with the Cosmos
C. J. Horowitz, A. Arcones, B. Côté +35
This is an exciting time for the study of r-process nucleosynthesis. Recently, a neutron star merger GW170817 was observed in extraordinary detail with gravitational waves and elec…
On the feasibility of employing solar-like oscillators as detectors for the stochastic background of gravitational waves
Daniel M. Siegel, Markus Roth
We present a hydrodynamic model that describes excitation of linear stellar oscillations by a stochastic background of gravitational waves (SBGW) of astrophysical and cosmological…
Excitation of stellar oscillations by gravitational waves: hydrodynamic model and numerical results for the Sun
D. M. Siegel, M. Roth
Starting from a general relativistic framework a hydrodynamic formalism is derived that yields the mean-square amplitudes and rms surface velocities of normal modes of non-relativi…
Excitation of non-radial stellar oscillations by gravitational waves: a first model
D. M. Siegel, M. Roth
The excitation of solar and solar-like g modes in non-relativistic stars by arbitrary external gravitational wave fields is studied starting from the full field equations of genera…
