The Astrobigné Organizing Committee is currently composed of Crescenzo Tortora (Questo indirizzo email è protetto dagli spambots. È necessario abilitare JavaScript per vederlo. , reference person for the extragalactic group), Nicoletta Sanna (Questo indirizzo email è protetto dagli spambots. È necessario abilitare JavaScript per vederlo. , galactic group), and Alessio Turchi (Questo indirizzo email è protetto dagli spambots. È necessario abilitare JavaScript per vederlo. , for the technological area), supported by our director Maria Sofia Randich and by the invaluable help of Emanuela Masini with the "real" stuff.


The Astrobigné concept:

Astrobigné is a series of short seminars that are held at the Osservatorio, with the goal of interconnecting the community of people working here, spreading new ideas and results, creating and reinforcing synergies between groups and indiduals. As such, Astrobigne's are meant to be accessible to a broad audience, including astronomers and technology staff, from senior researchers to students. Not by chance, the name "bigné" was chosen to designate something delicious, attractive, quick to grasp and easy to "eat".

In practice, the astrobigne talks:

  • must be short (10 minutes plus 5 for open discussion, strict, 6-8 slides at most)
  • must present only 1-2 key points that people can assimilate quickly should be aimed at triggering later discussions, collaboration, and future activities.
  • at this aim, can also present ongoing work with intermediate results can cover a broad range of topics, including astronomy, technology, historic research, public outreach, organization etc...
  • will NEVER present a general overview of the subject and a complete account of the speaker's work
  • are given in English whenever possible (this is not because we don't love Italian, but we all understand that English is our professional language to be used to foster international collaborations. Not to mention that here usually are non-Italians in the audience).

Astrobigne's take place on Tuesdays, every two weeks in the main auditorium of OAArcetri (Aula A). We usually have two bigne'-talks (10+5minutes each), selected by the organizing committee in order to cover as many different areas of interest as possible. Before the talks, at 11:45, we normally meet in Aula A to socialize and eat real bigne's (pastries!). The talks start at noon, but everybody is strongly advised to come by 11:45 so not to miss the... beginning of the talks!

The short and adventurous (in-space) life of a PLATO Science telemetry packet

PLATO has been selected and adopted by ESA as the third Medium-class mission of the Cosmic Vision Program to be flown in late 2026. It will detect and characterise exoplanets by means of their transit signature in front of a very large sample of bright stars, and will measure the seismic oscillations of the parent sun in order to understand the properties of exoplanetary systems down to rocky planets orbiting solar-like stars in their habitable zone. To achieve its main scientific goal, the PLATO Instrument, similarly to most other scientific payloads, has been designed to collect and transmit to Ground the raw scientific data in a complex and efficient way that requires a huge engineering work on HW and SW, sometimes unknown or overlooked by the Scientific Community in charge of exploiting the produced data. So, with my talk, I’ll try to highlight the "short and adventurous" life of a PLATO scientific telemetry packet, across the P/L HW and SW layers, before its transmission to Ground.
