Revealing the substellar population of IC 1396: A spectroscopic survey of brown dwarfs in the region
Belinda Damian, Jessy Jose, Aleks Scholz +7
We present a new spectroscopic view of the brown dwarf population in the young star-forming region IC 1396 and investigate the impact of environment on low-mass star formation. We…
RV and TTV Measurements of Two Transiting Long-Period Giants around TOI-4600
Tong Hu, Zitao Lin, Sharon X. Wang +27
TOI-4600b and c, originally identified by the Transiting Exoplanet Survey Satellite (TESS) and reported by I. Mireles et al. (2023), are a rare pair of transiting long-period giant…
The age sequence of young clusters in Perseus: Estimating ages from mass distributions
Tatiana Pavlidou, Aleks Scholz, Koraljka Muzic
Establishing ages for young clusters is key for properly tracking the star formation history of a region. In this paper we investigate a new approach to estimating ages for young p…
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…
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…
