An ongoing parallax microlensing event OGLE-1999-CAR-1 toward Carina.

MAO S.

Abstract (from CDS):

We study the first microlensing event toward the Carina spiral arm discovered by the OGLE collaboration. We demonstrate that this long duration event exhibits strong parallax signatures. Additional information from the parallax effect allows us to determine the lens transverse velocity projected onto the Sun-source line to be ∼145km/s. We also estimate the optical depth, event rate and duration distribution for microlensing toward Carina. We show that this event is broadly consistent with these predictions.
