BVRI light curve of OGLE LMC-ECL-11893
Listed in IVOA Registry (Virtual Observatory)
We report the serendipitous discovery of a disk-eclipse system OGLE-LMC-ECL-11893.
Description
The eclipse occurs with a period of 468 days, a duration of about 15 days, and a deep (up to {Delta}m_I_~1.5), peculiar, and asymmetric profile. A possible origin of such an eclipse profile involves a circumstellar disk.
The presence of the disk is confirmed by the H-alpha line profile from the follow-up spectroscopic observations, and the star is identified as Be/Ae type. Unlike the previously known disk-eclipse candidates, the eclipses of OGLE-LMC-ECL-11893 retain the same shape throughout the span of ~17yr (13 orbital periods), indicating no measurable orbital precession of the disk.
