APACHE Project’s News
The 3rd GAPS Project progress meeting has been held in Palermo on 24-25 October 2013, to present the last results of this relevant observing program conducted at TNG with the HARPS-N spectrograph and discuss future strategies for all the sub-programs. The APACHE team contributed with two talks, presented by A. Sozzetti and M. Damasso, introducing the audience to the APACHE survey and presenting the preliminary results about the targets jointly observed by GAPS and APACHE. The APACHE photometry could efficiently help in characterizing the activity of the M dwarfs and interpreting the spectroscopic data, possibly making the road to the detection of small mass planets less difficult.
This week end we had the great pleasure to have as our guest Zhaoxiang QI (Kevin, for friends) from the Shanghai Astronomical Observatory, Chinese Academy of Sciences. He is visiting our colleagues of INAF-OATo for two months, and he has been accompained to OAVdA by Mario Lattanzi, one of the members of the Apache tribe working in Torino. Kevin is an associate researcher expert in astrometry. He has worked for the LAMOST telescope (http://www.lamost.org/public/?locale=en) by providing astrometric support (pointing, tracking and guiding of the telescope and its focal plane, fiber positioning, survey strategy assisting…). Moreover, he provided astrometric support also for LUT, a Lunar-based Ultraviolet Telescope (http://adsabs.harvard.edu/abs/2011ScChG..54..558C). Kevin has showed great interest for the APACHE project and we spent some time together discussing in front of the telescope array. Unfortunately, due to the bad weather conditions, he could not see the telescopes in action. We thank Kevin for his visit and we invite him for another occasion, this time under a clear sky!
Andrea Bernagozzi, scientific researcher at the OAVdA and member of the APACHE research team, will give on Monday, March 25th a talk about extrasolar planets for a refresher course oriented towards Italian high school science teachers.
The talk will be presented at 15.30 hour at the Science Museum of the University of Camerino, Italy (http://www.unicam.it/museoscienzenaturali/docfile/seminari_per%20insegnanti_2013-1-2-3.pdf).
On 8th of March we had the pleasure to host dr. ZengHua Zhang at the Astronomical Observatory Of the Autonomous Region of the Aosta Valley (OAVdA). He has got his PhD at the Centre for Astrophysics Research (University of Hertfordshire).
ZengHua, during a brief permanence at the INAF – Astrophysical Observatory of Torino, has found the time to come to visit our Observatory and the APACHE telescope array. His research topics include the discovery and characterization of low mass stars and brown dwarfs in large area surveys, the study of the physical properties of disk and halo with benchmarks in binary systems, and the search for the extreme ultracool objects in near-infrared surveys. He gave a very interesting seminar for the OAVdA staff about the ultracool dwarfs in the Galactic Halo (see the picture, of course ZengHua is the one in the middle!), leaving us with an increased curiosity about such celestial objects and about the possibility of existence of planets orbiting ultracool dwarfs.
Here it is the personal Web page of ZengHua.
As recently reiterated in a paper by C. D. Dressing and D. Charbonneau (The Occurrence Rate of Small Planets around Small Stars, http://arxiv.org/abs/1302.1647), looking for habitable planets around low-mass stars is a very promising research field. The APACHE Project is working on it every night, when the sky collaborates. Since August, some of the M dwarfs stars observed by the APACHE telescopes are targets also observed by the spectrograph HARPS-N, hosted by the Telescopio Nazionale Galileo (TNG) at the top of La Palma island in the Canary archipelago, in the framework of the very ambitious, challenging and long-term observational programme GAPS (Characterizing the Global Architectures of Planetary Systems).
The APACHE Project will be presented at the “Hot Planets and Cool Stars” meeting which will be held at the Max Planck Institute for extraterrestrial Physics in Garching (Germany), from 12 to 16 November (http://www.mpe.mpg.de/events/ropacs-2012/Home.html).
Alessandro Sozzetti will have a talk on Tuesday 13th, and Jean Mark Christille will present the poster “THE APACHE Survey Hardware and Software Design: Tools for an Automatic Search of Small-size Transiting Exoplanets”.
As we reported yesterday in this post (here), we have participated at the GREAT-ESF Workshop “GAIA and Exoplanets: GREAT Synergies at the Horizons“ in Turin Nov 5-7, 2012.
In this post, almost in real time, you can find the presentation that we made at the conference.
The APACHE Project will be presented tomorrow (7th November, 2012 at session 2/3: 12.00-12.20) at the GREAT-ESF Workshop “GAIA and Exoplanets: GREAT Synergies at the Horizons in Turin Nov 5-7, 2012.
We will be there with an oral contribution of Mario Damasso, PhD Student at Doctoral School in Astronomy, University of Padova, and scientific researcher at the OAVdA:
The APACHE Project: searching for transiting planets around cool stars
Here you can find the abstract and more information.
and with a poster by Jean Marc Christille, PhD Student, University of Perugia and scientific researcher at the OAVdA:
THE APACHE Survey Hardware and Software Design: Tools for an Automatic Search of Small-size Transiting Exoplanets
Here you can find the abstract and more information
As soon as possible we will publish the slides and the poster.
As we reported a few weeks ago in this post (here), we have participated at the congress of the Italian Physical Society. In this post you can find the presentation that we made at the conference.
The APACHE team is presenting a poster at the European Planetary Science Congress 2012, which is held in Madrid (23-28 September, www.epsc2012.eu/information/general_information.html).
Paolo Giacobbe will show the milestones of the Project and discuss the recent developments presentig the work:
“Photometric transit search for planets around cool stars from the western Italian Alps: The APACHE survey” (http://meetingorganizer.copernicus.org/EPSC2012/EPSC2012-755.pdf)
