Hydrodynamic simulations of WD-WD mergers and the origin of RCB stars
Sagiv Shiber, Orsola De Marco, Patrick M. Motl +10
We study the properties of double white dwarf (DWD) mergers by performing hydrodynamic simulations using the new and improved adaptive mesh refinement code Octo-Tiger. We follow th…
Betelgeuse as a Merger of a Massive Star with a Companion
Sagiv Shiber, Emmanouil Chatzopoulos, Bradley Munson +1
We investigate the merger between a 16 solar mass star, on its way to becoming a red supergiant (RSG), and a 4 solar mass main-sequence companion. Our study employs three-dimension…
Peculiar Hydrogen-deficient Carbon Stars: Strontium-Rich Stars and the s-Process
Courtney L. Crawford, Patrick Tisserand, Geoffrey C. Clayton +1
Context: R Coronae Borealis (RCB) variables and their non-variable counterparts, the dustless Hydrogen-Deficient Carbon (dLHdC) stars have been known to exhibit enhanced s-processe…
R Coronae Borealis Star Evolution: Simulating 3D Merger Events to 1D Stellar Evolution Including Large Scale Nucleosynthesis
Bradley Munson, Emmanouil Chatzopoulos, Juhan Frank +4
R Coronae Borealis (RCB) stars are rare hydrogen-deficient carbon-rich variable supergiants thought to be the result of dynamically unstable white dwarf mergers. We attempt to mode…
Modeling R Coronae Borealis Stars: Effects of He-Burning Shell Temperature and Metallicity
Courtney L. Crawford, Geoffrey C. Clayton, Bradley Munson +2
The R Coronae Borealis (RCB) stars are extremely hydrogen-deficient carbon stars which produce large amounts of dust, causing sudden deep declines in brightness. They are believed…
