FASR Science
IDENTIFICATION OF EMISSION MECHANISMS!

	Nature & Evolution of Coronal Magnetic Fields
	Measurement of coronal magnetic fields – higher cadence – higher spec resln; preflare build-up and release; signature of preflare state; nature of trigger mechanisms
	Temporal & spatial evolution of fields
	Role of electric currents in corona
	MHD/other  oscillations & QPOs – “coronal seismology”
	Coronal Mass Ejections
	Birth & acceleration; shock formation; coronal cavity? Magnetic connectivity/toplogy & dynamics
	B, nrl, nth, T,  magnetic flux??
	Prominence eruptions
	Relation to SEPs & other SW predictors
	Chromo/coronal waves
	Flares
	solar/stellar connection/analogies
	Energy release – dm burst em mech/instability identification
	Plasma heating – microphysics of energy release
	Electron acceleration and transport – CME/dm connections?
	Origin of SEPs

FASR Science (cont)

	The “thermal” solar atmosphere
	coronal holes and streamers (low freq); fast CH evolution
	Coronal heating - nanoflares
	Thermodynamic structure of chromosphere in AR, QS, CH
	Formation & structure of filaments/prominences
	Transition between thermal/nonthermal AR
	Oscillations/response of convec zone
	Scudder
	Origin of Solar Wind??
	Birth in network – nanoflares?
	Tomography of inner heliosphere (if low-freq)
	Turbulence & waves in inner helio (if low-freq)
	Magnetic field constraints (… maybe – hard)
	Space weather, LWS, and synoptic studies

FASR Science (cont)

	As a comprehensive, dedicated solar instrument sensitive to magnetic fields, eruptive phenomena, their locations, and physical properties – and capable of  providing many of these in real time or near-real time - FASR is an excellent LWS/Space Weather instrument.
	As a stable, well-calibrated instrument FASR will make important contributions to synoptic studies: long term monitoring of magnetic, thermal, and irradiance properties of the Sun.
