Remarks
Some references may be clicked to view in new window. Roll over index number to view submission details.
1 Otero, Sebastian Alberto Orbital period in reference is 250.3 d. but it's not the photometric period in ASAS-3 data. Only one minimum is seen so variability is caused by reflection. Pulse period is 853.4 seconds.
