Descripción
OO Serpentis is a deeply embedded young star which brightened by 5 mag
in Kband between 1994 and 1995, and gradually faded afterwards. In many
respects the star and its outburst is very similar to the well-known
young eruptive stars (FUors and EXors). We monitored the eruption of OO
Ser for 20 months with the Infrared Space Observatory in the 3.6-100
μm wavelength range. We complemented this dataset with new
(ground-based and spaceborn) infrared observations from 2004 and
constructed the light curve of the outburst at 10 different wavelengths.
Our results show that by 2004 OO Ser already returned to the
pre-outburst state at 2.2 μm, suggesing a significantly shorter
outburst timescale than that of classical FUors, but longer than that of
EXors. This may indicate that OO Ser -- together with the recently
erupted star V1647 Ori -- is the first example of an intermediate object
between FUors and EXors.
