discovery method
way an exoplanet was discovered

Description	discovery method of an extrasolar planet
Represents	method of detecting extrasolar planets (Q591022)
Data type	Item
Template parameter	Template:Infobox planet discovery_method
Domain	According to this template: extrasolar planet According to statements in the property: exoplanet (Q44559), brown dwarf (Q101600), extrasolar moon (Q679411) or sub-brown dwarf (Q1073768) When possible, data should only be stored as statements
Allowed values	According to this template: a limited number of items as for example Doppler spectroscopy (Q2273386), transit method (Q2069919), transit-timing variation (Q2945337), gravitational microlensing (Q1028022), polarimetry (Q899381), astrometry (Q181505) According to statements in the property: Doppler spectroscopy (Q2273386), transit method (Q2069919), transit-timing variation (Q2945337), gravitational microlensing (Q1028022), astrometry (Q181505), direct imaging (Q15279026), pulsar timing (Q42364577) or variable star timing (Q113570226) When possible, data should only be stored as statements
Example	HAT-P-7b (Q1328150) → transit method (Q2069919) 14 Andromedae b (Q1039721) → Doppler spectroscopy (Q2273386) Kepler-41b (Q15114570) → transit method (Q2069919)

Broadening scope

Should this be broadened to things other than exoplanets? There are likely many items (or statements) that could usefully have their discovery method indicated (fundamental particles, species, elements). T.Shafee(evo&evo) (talk) 02:53, 4 November 2020 (UTC)
