μFUN-PLANET collaboration

 

In January 2009 we decided to form a new microlensing collaboration, the μFUN-PLANET collaboration. Our objective is  to  search for extrasolar planets via microlensing, combining the ressources of the two previous groups, μFUN and PLANET. μFUN and PLANET had different search strategies based primarily on different resource structures. Nevertheless, the strategies are both complementary and overlapping and so will benefit from increased cooperation and integration of effort.
In particular, coverage of high-mag events  will benefit in two major ways:
  1) better identification of high-mag events from PLANET photometry at low magnification.
  2) better coverage near peak by closer coordination between μFUN and PLANET observatories.

We will, as always, work closely with OGLE and MOA teams.

 

2012 season

μFUN-PLANET came online mid march 2012. μFUN and some PLANET telescopes were kept on target of opportunity status; Continuous monitoring for Planet started mid May 2012 at Canopus, and later at SAAO.

Planet season ended officialy on September 1st, but a few promizing alerts have been followed later by Canopus, thanks to the Tasmanian team.

Official data collecting ended November 11. A summary of all observations for 2012 can be found at: 2012 summary

Some 22 or more possible planets have been detected, but confirmation is requested for most of them. This is more than ever before. The ┬Álensing community is reprocessing the data and doing exhaustive fitting on them. Among the more promising:

OGLE-2012-BLG-0026 might be a multiple system with masses of 0.12 MJ and 0.70 MJ orbiting a G-type main sequence star with a mass 0.9 M.

OGLE-2012-BLG-0358 a planetary-mass object orbiting a brown dwarf (3.2 MJ and 1.9 MJ)

MOA-2012-BLG-403 a candidate free-floating planet, tE≅2 days

We are collaborating intensely with Cheongho Han and his group, both for observations and modelling (real time and offline).

2013

     The new telescope in Tasmania, Australia is under mounting at Bisdee Tier. Plans include a wide field imager. After arriving to Hobart in November 2012, the new telescope has been assembled at UTAS, then moved to the new observatory .
It received its mirror end of 2012.

     The Greenhill Bisdee Tier Observatory opening will be officiated by the Governor at the Observatory on the morning of Saturday 23 February 2013.

     On Jan 13, 2013, the big bush fire in west Australia ran very close from the Sky Mapper Dome in Siding Spring. The temperature just outside the dome rised above 100 °C . Fortunatly, no telescopes were damaged, as it happened in the 2003 firestorm, but some images are impressive (see astropixies )

    For the 2013 hunting season, besides the traditional List of monitored events (with online data files), a new facility is available for planet hunters: ALOHA is developped as part of HOLMES fast utility to have a glimpse on OGLE, MOA and SkyMapper data to pin down anomalous events and switch rapidly to intense observing.
Data from OGLE and MOA (and later SkyMapper) collected by Planet are analysed by E. Bachelet in Toulouse (France), and displayed on the fast plotting utility built by Jadzia Donatowicz in Vienna.

ALOHA is still under development but some functionalities are already fully operational : selection of high magnification events, free floating planet candidates, anomalous events. Have a try with ALOHA to see real time what are the best high magnification candidates, anomalous microlensing events and free floating planet candidates here

     MOA alerted the first event of the 2013 Bulge season on Feb. 7. Among the first bunch of alerted events, MOA-2013-BLG-016 is also one of the last events observed by OGLE last year: OGLE-2012-BLG-1724. A kind of continuity

 


ONLINE DATA
can be accessed through our List of monitored events (with online data files).
Usually data updates within an hour of being taken at the Planet telescopes.
Data will be still uploaded on both websites of PLANET and μFUN for the time being.

OGLE Survey group in Chile. They are currently upgrading thier telescope. A list of pre 2009 events
MOA Survey group in New Zealand. A list of thier current microlensing alerts
μFUN Follow up group of Ohio State Uni, and amateur astronomers world wide. A quick-look photometry archive
RoboNet II Automatic follow up telescope network with customizable priority list for microlensing targets
and associated page that provides a telescope specific prioritized list. PLOP
MiNDSTEp and ARTEMIS consists of an automatic data collection, modelling and alert detection system. It has similar layout/methedology/functionality as the PLANET pages (above) but there are differences in the implementation of models.
There is a sorted prioritized list
and an interactive plotter

not Found At IAP, PLANET is funded by HOLMES collaboration (J.P. Beaulieu, Pascal Fouqué)

 
Planet Planet has found the first earth-like exoplanet Information available.
