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…
Is Betelgeuse the Outcome of a Past Merger?
E. Chatzopoulos, Juhan Frank, Dominic C. Marcello +1
We explore the possibility that the star alpha Orionis (Betelgeuse) is the outcome of a merger that occurred in a low mass ratio (q = M2/M1 = 0.07 - 0.25) binary system some time i…
Precise Measures of Orbital Period, Before and After Nova Eruption for QZ Aurigae
Bradley E. Schaefer, David Boyd, Geoffrey C. Clayton +7
For the ordinary classical nova QZ Aurigae (which erupted in 1964), we report 1317 magnitudes from 1912--2016, including four eclipses detected on archival photographic plates from…
Numerical Simulations of Mass Transfer in Binaries with Bipolytropic Components
Kundan Kadam, Patrick M. Motl, Dominic C. Marcello +2
We present the first self-consistent, three dimensional study of hydrodynamic simulations of mass transfer in binary systems with bipolytropic (composite polytropic) components. In…
Evolving R Coronae Borealis Stars with MESA
Amber Lauer, Emmanouil Chatzopoulos, Geoffrey C. Clayton +2
The R Coronae Borealis (RCB) stars are rare hydrogen--deficient, carbon--rich supergiants. They undergo extreme, irregular declines in brightness of many magnitudes due to the form…
