SHARK-NIR on-sky: Early Science phase

SN-ES-1 (October 24th - 29th, 2023)

Early science run 1: Coronagraphic images acquisition of scientific targets with debris disk searching for companion, with disk in Taurus region and with strong PMa signal.

SHARK-NIR team on the mountain: Luca Marafatto, Jacopo Farinato, Alessandro Lorenzetto, Daniele Vassallo, Simone Di Filippo, Fulvio Laudisio , Tania Sofia Gomes Machado.

SHARK-NIR Remote team (after dome opening): Dino Mesa, Elena Carolo, Domenico Barbato, Valentina D'Orazi, Maria Bergomi.

MWC758 disk

The disk of MWC758 as imaged by SHARK-NIR.

The two known spirals arms are clearly visible. It is thought that these structure are caused by the presence of a hidden low-mass companion (not visible in our image).

We performed a 80 min observation in CI mode with the Gaussian Lyot coronagraph. Data reduction was performed with 5 modes PCA technique.

SN-ES-2 (December 23rd, 2023 - January 5th, 2024)

Early science run 2: Coronagraphic images acquisition of scientific targets with disk and jets searching for companion, with strong PMa signal and for searching additional companion of known transiting planet. Direct imaging on debris disk.

SHARK-NIR team on the mountain: Simone di Filippo, Paolo Cerpelloni, Tania Sofia Gomes Machado

SHARK-NIR Remote team (after dome opening): Jacopo Farinato, Domenico Barbato, Elena Carolo, Daniele Vassallo, Gabriele Umbriaco, Dino Mesa, Alessandro Lorenzetto.

SN-ES-3 (February 4th - 9th, 2024)

Early science run 3: Coronagraphic images acquisition of scientific targets with disk and possible companion, with strong PMa signal, for searching stellar or BD companions and photometry of known stellar companion.

SHARK-NIR team on the mountain: Simone di Filippo, Paolo Cerpelloni, Tania Sofia Gomes Machado, Alessandro Lorenzetto, Dino Mesa.

SHARK-NIR Remote team (after dome opening): Domenico Barbato, Elena Carolo, Jacopo Farinato, Fulvio Laudisio, Daniele Vassallo, Maria Bergomi.

SN-ES-4 (February 18th - 23th, 2024)

Early science run 4: Coronagraphic images acquisition of scientific targets with strong PMa signal and for searching exoplanets around young stars. Spectroscopic images for characterization of known low-contrast stellar/BD companion. Direct imaging on satellites and snapshot searching for young BD companion to T Tauri star.

SHARK-NIR team on the mountain: Simone di Filippo, Jacopo Farinato, Federico Battaini, Alessandro Lorenzetto, Domenico Barbato.

SHARK-NIR Remote team (after dome opening): Dino Mesa, Daniele Vassallo, Elena Carolo, Maria Bergomi, Luca Marafatto, Paolo Cerpelloni, Fulvio Laudisio.

Target with strong PMa signal

The external bright companion is stellar and could justify the signal.

The inner companion is in the planetary/ BD mass range (according to the system age, TBD) and need further confirmation.

SN-ES-5 (May 21st - 22nd, 2024)

Early science run 5: Coronagraphic images acquisition of scientific targets with strong PMa signal, for searching stellar or BD companions and photometry of known stellar companion.

SHARK-NIR team on the mountain: SHARK-NIR team will perform all observations remotely from INAF - Astronomical Observatory of Padua

SHARK-NIR team remotely connected: Alessandro Lorenzetto, Daniele Vassallo, Dino Mesa, Domenico Barbato, Elena Carolo, Fulvio Laudisio, Jacopo Farinato, Luca Marafatto, Paolo Cerpelloni, Simone di Filippo, Tania Sofia Gomes Machado.

INAF (February 22nd - 23rd, 2025)

One of the INAF run, where IO was observed with both SHARKS: SHARK-NIR and SHARK-VIS.

Io is one of Jupiter's largest moons and is renowned for its extremely active volcanoes, making it the most geologically active body in the solar system.

SN-ES-6 (April 9th-11th & 15th-17th, 2025)

Early science run 6: Coronagraphic images acquisition of scientific targets with strong PMa signal, in young planetary systems and with transition disk.

SHARK-NIR team on the mountain: Elena Carolo, Jacopo Farinato, Alessandro Lorenzetto, Luca Marafatto, Lorenzo Merli, Dino Mesa.

SN-ES-7 (May 6th-8th & 16th-18th, 2025)

Early science run 7: Coronagraphic images acquisition of scientific targets around planet-hosting stars, with strong PMa signal, with debris disk and astrometric calibration.

SHARK-NIR team on the mountain: Domenico Barbato, Maria Bergomi, Simone di Filippo, Cecilia Lazzoni, Alessandro Lorenzetto, Luca Marafatto, Lorenzo Merli.
