| Abstract: |
The GAPS (Global Architecture of Planetary Systems) project is a, mainly
Italian, effort for the comprehensive characterization of the
architectural properties of planetary systems as a function of the host
stars' characteristics by using radial velocities technique.
Since the beginning (2012) the project exploited the HARPS-N high
resolution optical spectrograph mounted at the 4-m class TNG
telescope in La Palma (Canary Islands). More recently, with the upgrade
of the TNG near-infrared spectrograph GIANO-B, obtained in the
framework of the GIARPS project, it has become possible to perform
simultaneous observations with these two instruments, providing
thus, at the same time, data both in the optical and in the
near-infrared range.
The large amount of data obtained in about 5 years of observations
provided various scientific outputs, and among them, time series of
radial velocity (RV) profiles of the investigated stellar systems.
This contribution shows the first steps undertaken to deploy the GAPS
Time Series as an interoperable resource within the VO framework
designed by the IVOA.
This effort has thus a double goal. On one side there's the aim at
making the time series data (from RV up to their originating spectra)
available to the general astrophysical community in an interoperable
way. On the other side, to provide use cases and a prototyping base
to the ongoing time domain priority effort at the IVOA level.
Time series dataset discovery, depicted through use cases and mapped
against the ObsCore model will be shown, highlighting
commonalities as well as missing metadata requirements.
Future development steps and criticalities, related also to the joint
discovery and access of datasets provided by both the spectrographs
operated side by side, will be summarized. |
