discov_num	notes	refcode
RST5219	Pre-main sequence star HBC 515, located in the Orion L1622 cometary
HBC 515	cloud. The primary appears to be comprised of two ~equal brightness
	weakline T Tauri stars of spectral type K2V. The B component dominates
	the system at mid-infrared wavelengths, suggesting that it is a
	protostar still embedded in the nascent cloud of HBC 515. The C and D
	components (L1622-6 and L1622-6N) are also T Tau stars and likely
	physically associated.	Rep2010
