Current service activities

Gaia Follow-Up Network of Solar System Objets 2013-now

I am the responsible of the DU459, which is the development unit within ESA Gaia DPAC in charge of the dissemination of alerts on newly discovered solar system objects.

Our activities consist in organizing a network of observers around the world, and providing them with predicted position of discoveries (ephemeris). For that, we organized three workshops in Paris in 2010, 2012, and 2014. In parallel, we developed an automated pipeline to ingest data from Gaia, and to provide a convenient access to observers (see the web pages).

Development of ephemerides services 2008-now

I participate to the development of ephemeris services at the IMCCE. My contributions are mainly focused on the physical ephemeris (i.e., apparent flux, apparent shape) and are natively included in the VO services, such as Miriade.

Past activities

Ephemeris: Extension of SkyBoT to space missions 2016

During my research fellowship at ESA, we initiated the development of an extension of the VO service SkyBoT to use it to identify Solar System Object in images taken from space missions. We first integrated the ESA Rosetta mission, searching for serendipitious observations of asteroids by the OSIRIS camera (Carry et al., 2012). In support to the Kepler/K2 community, we recently released this SkyBoT extension, with both ESA Rosetta and NASA Kepler missions available. (Berthier et al., 2016).

Ephemeris: ESO Phase II for Solar System Objects 2015

Together with J. Berthier (IMCCE), we built a customized output to the VO service Miriade to be directly fed into ESO VLT software P2PP for the observation of moving objects. This output can be generated with the option --pafParams, or using a dedicated web form, hosted on both ESO's and IMCCE's web pages (Carry & Berthier, 2016, see the ESO announcement). You can also download the form sources here.

Ephemeris: Thermal flux of asteroids 2014

Together with J. Berthier (IMCCE) and M. Delbo (OCA), supported by the VO Paris Data Centre of the Paris observatory, we have integrated the NEATM thermal model (Harris, 1998) into the IMCCE/Eproc ephemeris software. Thermally emitted flux can be computed for any asteroid, at any epoch, any wavelength using the VO service Miriade with the option --thermalFlux (Example).
