In 1985, a
group
was established at
our institute,
with the
aim of using the technique of lunar occultations
in the near IR for high angular resolution. Since then, a program
of LO observations is active at the
TIRGO Observatory.
In parallel, numerous
collaborations have been established, with
several other
observatories
and researchers in the world.
The current
archive
includes several hundreds
occultations. The
results
cover the fields of binary stars (both on the main sequence and
among young stellar objects), stellar angular diameters and
circumstellar envelopes.
Observations are carried out almost exclusively in the near IR, by means either of fast InSb photometers such as FIRT and FIRPO, or of Nicmos-based IR cameras which can be read out at high speed in a subarray, such as ARNICA and MAGIC.
