Stellar-MADE Project

Exploring the effects of Stellar Multiplicity on planet formation Across Disc Evolution.
ERC Starting Grant: October 2022 - September 2027.
Hosted at IPAG & UGA (Grenoble, France).

Project goals:

• Establish the formation channels of protoplanetary discs around young stellar objects;
• Follow disc dynamics and grain growth to identify the regions of planetesimal formation;
• Characterise planetary architectures and the resulting exoplanet population.

Stellar-MADE co(s)mic strips

A series of comic strips about different aspects of the science carried out within the Stellar-MADE project. The 4 episodes were originally prepared in French (FR) by Nicolás Cuello & Antoine Alaguero in collaboration with the Ink Link and Séverine Alvain (during 2023 and released in 2024 and 2025). Then, Elisa Castro took care of the translations into Spanish (ES), English (EN) & Italian (IT). We regularly use this comic during outreach activities in schools.

1. Daily life of an astrophysicist, models & astronomical observations: EN1, FR1, ES1, IT1.
2. Disc dynamics and planet formation in multiple stellar systems: EN2, FR2, ES2, IT2.
3. Distances & detection of exoplanets in multiple stellar systems: EN3, FR3, ES3, IT3.
4. Alien life, planetary orbits & chaos in multiple stellar systems: EN4, FR4, ES4, IT4.
