class vspec_vsm.StellarFlare(fwhm: astropy.units.Quantity, energy: astropy.units.Quantity, lat: astropy.units.Quantity, lon: astropy.units.Quantity, Teff: astropy.units.Quantity, tpeak: astropy.units.Quantity)

Bases: object

Class to store and control stellar flare information

Parameters:

• fwhm (astropy.units.Quantity) – Full-width-half-maximum of the flare

• energy (astropy.units.Quantity) – Time-integrated bolometric energy

• lat (astropy.units.Quantity) – Latitude of flare on star

• lon (astropy.units.Quantity) – Longitude of flare on star

• Teff (astropy.units.Quantity) – Blackbody temperature

• tpeak (astropy.units.Quantity) – Time of the flare peak

fwhm

Full-width-half-maximum of the flare

Type:

astropy.units.Quantity

energy

Time-integrated bolometric energy

Type:

astropy.units.Quantity

lat

Latitude of flare on star

Type:

astropy.units.Quantity

lon

Longitude of flare on star

Notes

Flare lightcurve profiles are calculated using the xoflares package [1]. In order to keep the multiwavenlength model self-consistent, we model a flare as a constant temperature surface that emits blackbody radiation. The lightcurve is created as the surface area grows, then decays.
