[Mesa-users] Pgstar Kippenhahn diagram log M vs log R

[Rob Farmer]

Hi,
No the pgstar kippenhan only works with the star's age as the xaxis (though
the one you show is also showing a time based quantity as your star is
gaining mass) and mass as the y axis.

MESA can output the data needed to do a radial kippenhan if you include:
mix_relr_regions 20
burn_relr_regions 20

in your history output. The pgstar's kippenhan plotter can not use that
data but you could try my python package
https://github.com/rjfarmer/mesaplot which can.

import mesaPlot as mp
m=mp.MESA()
m.loadHistory()
p=mp.plot()
p.plotKip3(m,xaxis='star_age',yaxis='radius',age_log=True,y1log=True)

Should work to give log age vs log radius
