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…
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…
Spectroscopy of Free-Floating Planetary-Mass Objects and their disks with JWST
Belinda Damian, Aleks Scholz, Ray Jayawardhana +6
Free-floating planetary-mass objects (FFPMOs) are known to harbor disks at young ages. Here, we present 1-13 spectra for eight young FFPMOs with masses of 5-10 M$_\mathrm{Jup…
Detection of Hydrocarbons in the Disk around an Actively-Accreting Planetary-Mass Object
Laura Flagg, Aleks Scholz, V. Almendros-Abad +6
We present the 0.6--12-micron spectrum of Cha\,1107-7626, a 6-10 Jupiter-mass free-floating object in the 2\,Myr-old Chamaeleon-I star-forming region, from observations with…
