transit_duration¶

stash.transit_duration(R_star, R_planet, orbital_period, semimajor_axis, impact_parameter)[source] [edit on github]¶

Compute transit duration from first through fourth contact given orbital and physical parameters.

Parameters:	R_star : `Quantity` Stellar radius R_planet : `Quantity` Planet radius orbital_period : `Quantity` Orbital period semimajor_axis : `Quantity` Orbital semimajor axis impact_parameter : float Impact parameter (-1, 1)
Returns:	duration : `Quantity` Transit duration from first through fourth contact.
