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…
The dawn of a new era for dustless HdC stars with GAIA eDR3
P. Tisserand, C. L. Crawford, G. C. Clayton +7
Decades after their discovery, only four hydrogen-deficient carbon (HdC) stars were known to have no circumstellar dust shell. This is in complete contrast to the 130 known G…
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…
