Host-star metallicities and kinematics of directly imaged brown-dwarf companions

C. Swastik, R. K. Banyal, M. Muduli +15

Brown dwarfs are common as free-floating objects but rare as close companions to Sun-like stars, a disparity known as the "brown-dwarf desert". Host-star metallicity can constrain…

JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates

G. Cugno, M. Benisty, R. Teague +32

Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…

Gravitational instability in planet-forming discs

Cristiano Longarini, Giuseppe Lodato

During the earliest phases of star and planet formation, a young star is surrounded by a disc that can become gravitationally unstable. Indeed, if the protoplanetary disc is suffic…

Extending dynamical mass measurements: probing GI as a possible origin of mm-dust spirals

V. Pezzotta, S. Facchini, A. F. Izquierdo +7

Constraining the total mass of protoplanetary disks is crucial to determine the availability of material for planet formation. Yet, providing accurate and precise measurements of t…

Far-ultraviolet flux distribution in Orion and its relation to stellar accretion

Rossella Anania, Andrew J. Winter, Miguel Vioque +8

Orion is the closest region hosting active star formation and young OBA stars. Computing far-ultraviolet (FUV) fluxes at its stars is essential to connect stellar and protoplanetar…

X-Shooter survey of disk accretion in Upper Scorpius II. A lack of correlation between accretion rates and disk properties

A. Empey, C. F. Manara, R. Garcia Lopez +19

The evolution of protoplanetary discs is intertwined with the process of planet formation, growth and migration. Studies of nearby star forming regions of different ages and proper…
