Dusting for the fingerprints of young exoplanets
Exoplanets forming in protoplanetary disks leave an impact on the circumstellar dust.
Millennium Nucleus on Young Exoplanets and their Moons
Unveiling a new population of exoplanets.
The Millennium Nucleus on Young Exoplanets and their Moons (YEMS) is an astronomy-informatics multidisciplinary effort funded by Iniciativa Científica Milenio and hosted by four universities in Chile. YEMS scientific objectives involve detecting and characterizing young exoplanets and exomoons to answer the long-standing question of their formation.
Can we witness the formation of an exoplanet?
Until three decades ago, scientists were skeptical that we would ever be able to find planets outside the solar system (exoplanets). Today, advances in technology and techniques have allowed the discovery of thousands of exoplanets and arrived at the astonishing statistics that most stars in our Galaxy are surrounded by planets. Understanding what makes a planet, when and where, which elements are abundant and which conditions prevail, means understanding its formation history.
Can we look for life on exoplanet moons?
The formation of planets and moons are intimately related, which means that moons can help us understand the origin of a planet. Moreover, most of the candidate places to look for life in our Solar System are in the giant planet's moons. Jupiter, for example, is not in the habitable zone but the moons of Jupiter, like Europa, are prime targets to study life.

Research
YEMS scientific objectives involve detecting and characterizing young exoplanets and exomoons to answer the long-standing question of their formation and pave the way to explore alternative habitable places.
Direct detection of exomoons.
Satellite systems provide fundamental insights into the formation pathway of their host exoplanets. The detection and monitoring of such satellites is important for us to understand how planets are formed.
Revealing the kinematics of planet formation
Exoplanets forming in protoplanetary disks modify the velocity field of the gas around them, leaving an observable impact on the gas kinematics.
Machine learning applied to astrophysics.
Astronomy relies upon special techniques to study the cosmos. Here we investigate how we can apply new developments in informatics to improve our tools in astrophysics.
Publications
YEMS researchers have led several works at the forefront of research.
First detection of Gravitational Instability at Planetary Scales
Weber et al. 2023b presents VLT observations of the system called V960 Mon, a young star that suddenly increased its brightness. Archival ALMA data reveals that the environment around this star is fragmenting...
Binary Protostar HBC 494 via ALMA
Nogueira et al. (2023) resolves and studies the binary components of the outbursting protostellar object HBC 494 with ALMA.
Review on planet formation in systems of multiple stars.
Zurlo et al. (2023) provides an invited review article for the European Physical Journal Plus. The article compares the fascinating observations of multiple stellar systems and discusses the potential and conditions for planet formation therein.
Twin disks observed in polarised light
Weber et al. (2023) presents observations of the structures around multiple stars obtained with the Chile-based Very Large Telescope. It analyses the observed effects where two protoplanetary disks coexist close to one another.
Interdisciplinary activities beyond scientific research
YEMS is involved in several projects on outreach, education, multicultural astronomy, and art.
Concierto Cielos
Combines musical art and performance with astrophysics research and talks.
Astrodiálogos
Potentiating intercultural dialogues via astrophysics.
CIRAS Pedagogical Team
Filling the gap between the frontiers of science and the classroom.
CMB Live Media Performance
Digital immersive media performance, with participation of YEMS members.
Science team
The YEMS Nucleus is born to provide a stage in which young researchers and students can fully develop their potential while producing great science.
