Science
Nice Results
- Halley's comet is still observed! in March 2003, at the distance of
Neptune. This was also the "Astronomy Picture of the Day" on Oct.3.
I had also observed that comet in 1994, as it
passed the halfway mark (January 1994): observation of the
faintest solar system object ever observed. [at that time]. In 1991, I
detected a majour outburst on the comet - which should have been quiet
at that time. This outburst created some waves in the public. For
instance, a lady contacted me to ensure me that this was a direct
cause (or was it a consequence?) of the Gulf war. Also, a journalist
concluded that the comet had completely exploded (which in turned
caused some
additional comments-in
french in this example).
- Comet Hale-Bopp is still very active, esp. considering the
distance at which it is now. We observed it at the 2.2m at ESO in
Mar.2001; here is a nice color
image (and is also available in
Italian, in
Hebrew
elsewhere...). It was also an
"Astronomy
Pic. of the Day".
- The object 2000 OF8 was discovered as an asteroid. We found out
that it is really a comet
-
The Trans-Neptunian Object 1996 TO66 has been extensively
observed; we obtained many interesting resulst on that object,
including its rotation period. This is described in
an ESO
Press Release, and in more details in one of
my papers.
- A strange supernova, sn 1998 bw, which seems to be related
to a Gamma Ray Burst (May
98). An ESO
Press Release has been published on that object.
-
Volcanoes on
Io, using the UH adaptive optics instrument on the CFHT.
-
Observations of Comet Hale-Bopp.
The IfA
Hale-Bopp page contains plenty of info and links about that comet;
for nice pictures, check out
the Images
and Spectra page.
-
Rapid Changes in the Inner Coma of
Comet Hyakutake (March 1996):
acrobatic observations of this nice comet with a great telescope and a
great seeing!
- Comet 1992a Helin-Alu, a nice distant comet, on
its discoverer page.
-
The discovery of a Transneptunian Object: 1994
TG2 (October 1994): one more TNO (only about 60 were known at that time), but I
discovered this one :-)
- High Resolution HST Images of Pluto
and Charon (May 1994): the first detailed, direct look at
Pluto and Charon's surface.
Trans-Neptunian Objects

Programs
-
POS1/Astromet:
an ESO/MIDAS package for astrometric calibration of scientific image (plates
and CCD); it can get its USNO/A1 standard stars automatically through the
net.
- TMAG:
an ESO/MIDAS package for photometric calibration of CCD images, with
quasi-automatic identification of Landolt's stars, and interactive
edition of bad points.
- MeteoMonitor,
a web-tool to monitor the conditions at ESO/La Silla. A separate version is now available for ESO/Garching.
-
Astrolabe Generator, a web-tool to produce "astrolabes" for your
site (updated version at eso.org.
The one at IfA is outdated).

On this page, you will find the whole,
email exchange constituting the Car 42 Saga. This is part of
the ESO folklore, probably of no interest for outsiders...
Marie-Claire, my wife, has her own page
at the Canada-France-Hawaii Telescope,
with plenty of palmtrees and aloha. Note that she is now working for
Gemini.
There was a nice article about her in
the July 98 "Ciel & Espace" (sorry, no English version).
Note that this is a private page; whatever you find here is
under my responsibility, not ESO's.
