Explanation of the figures
Two directories: Conservative vs. β = 0.5 : these directories show the different plots for conservative mass transfer and for mass transfer with a constant accretion efficiency (β) of 50%.
In every directory there are 2 kinds of data, unbinned (where every dot resembles a system, but not every system has the same probability) and binned (the data is binned and the colors indicate the probability).
Unbinned data
Red = All normal systems (primary becomes first a WD)
Green =All reversed systems (secondary becomes first a WD: so M1/Mwd1 is WD which is formed first)
Blue = Doubles: 2 WDs are formed simultaneously
binned data
No distinction is made between reversals and doubles. M1 and Mwd is always the initially most massive star.
♠ Conservative ♠
Unbinned data
Systems that form (minimum) 1 WD
Systems that form 2 WDs
To know more about the evolution:
Is it case A, B or C mass transfer?
What about the secondary? Is it case A, B or C mass transfer? (NEW)
Is it case A, B or C mass transfer? Zoom in on systems that form WDs with a mass higher than 0.48 Msun
Is the donor a star on the MS or on the AGB?
Added the systems which form a double spiral-in or are semi-reversals
binned data
Systems that form 2 WDs
Different groups can be distinguished:
Specification of the different groups
Figures below show the different groups:
⇒ Mwd1 vs Mwd2
⇒ Mwd1 vs a
♠ β = 0.5 ♠
Unbinned data
Systems that form (minimum) 1 WD
Systems that form 2 WDs
binned data
⇒ Specific Systems (NEW)
⇒ Comparison with the different groups
A poster whas shown during the conference: 370 Years of Astronomy in Utrecht (April 2-5,2012), which displayed the preliminary results (| poster | ).
