EWOCS-VIII: Internal kinematics and expansion of Westerlund 1 from VVVX proper motions
C. Ordenes-Huanca, A. Bayo, M. Guarcello +12
Westerlund 1 (Wd1) is the most massive young star cluster known in the Milky Way and a key laboratory for studying the early dynamical evolution of massive clusters. Owing to its h…
EWOCS-VI: Probing the hidden intermediate-mass population of Westerlund 1
C. Ordenes-Huanca, A. Bayo, M. Guarcello +11
Context: Westerlund 1 (Wd1), the most massive young star cluster in the Milky Way, is an excellent laboratory for studying star formation and early stellar evolution in a starburst…
Substellar population of the young massive cluster RCW 36 in Vela
A. R. G. do Brito do Vale, K. MužiÄ, H. Bouy +10
The initial mass function (IMF) is a cornerstone of star formation studies, yet its universality remains debated. We investigate the IMF in the young massive cluster RCW 36, locate…
Discovery of an Accretion Burst in a Free-Floating Planetary-Mass Object
V. Almendros-Abad, A. Scholz, B. Damian +7
We report the discovery of a long-lasting burst of disk accretion in Cha J11070768-7626326 (Cha 1107-7626), a young, isolated, 5-10 M object. In spectra taken…
Internal dynamics and structure of Cepheus OB4. The asymmetric expansion of Berkeley 59
Bruno Wiesneth, Koraljka Muzic, Victor Almendros-Abad
Accurate measurements of young stellar cluster internal dynamics provide crucial insights into their formation. With Gaia, we are now able to trace stellar motions and study the dy…
The substellar population in Corona Australis
Koraljka Muzic, VÃctor Almendros-Abad, André Baptista +7
The substellar initial mass function (IMF) and the formation mechanisms of brown dwarfs (BDs) remain key open questions in star formation theory. IMF characterization in a large nu…
