POPCORN: Case A, B or C? (ZOOM)



Explanation of the figures

The plots are shown in the case of conservative mass transfer for all the systems that form WDs with a mass higher than 0.48 Msun. The different cases of mass transfer (for the primary star) are highlighted.


Data

Red = All systems
Green = Case A (no distinction made between A and AB)
Blue = Case Br
Pink = Case Bc
Light blue = Case C
Yellow = Case BrB
Black = Case BcB
Orange = Case CB

Comment1: Second B means: The primary fills Roche lobe again as a He-star. (Therefore CB: first case C (when star on E-AGB and fills it again as a He-giant))
Comment2: When He-star fills the Roche lobe, no distinction is made if this is stable or not
