Schmidt Law
Plots star formation surface density vs. gas surface density including the observed relationships. Currently, only plots densities found in radial annuli.
Usage:
>>> import pynbody.plot as pp >>> pp.schmidtlaw(h[1])
Optional keyword arguments:
- center: bool
center and align the input simulation faceon.
- filename: string
Name of output file
pretime (default=’50 Myr’): age of stars to consider for SFR
- diskheight (default=’3 kpc’): height of gas and stars above
and below disk considered for SF and gas densities.
rmax (default=’20 kpc’): radius of disk considered
- compare (default=True): whether to include Kennicutt (1998) and
Bigiel+ (2008) for comparison
radial (default=True): should bins be annuli or a rectangular grid?
bins (default=10): How many radial bins should there be?
- legend: boolean
whether to draw a legend or not
