Variability in SSTc2d J163134.1-240100, a brown dwarf with quasi-spherical mass loss
Aleks Scholz, Koraljka Muzic, Victor Almendros-Abad +4
We report on a search for variability in the young brown dwarf SST1624 (~M7 spectral type, M~0.05Msol), previously found to feature an expanding gaseous shell and to undergo quasi-…
Spectroscopic substellar initial mass function of NGC 2244
V. Almendros-Abad, K. Mužić, H. Bouy +10
We aim at characterizing the low-mass (sub)stellar population of the central portion (2.4 pc) of the 2 Myr old cluster NGC 2244 using near infrared spectroscopy. By study…
Disks around young planetary-mass objects: Ultradeep Spitzer imaging of NGC1333
Aleks Scholz, Koraljka Muzic, Ray Jayawardhana +2
We report on a sensitive infrared search for disks around isolated young planetary-mass objects (PMOs) in the NGC1333 cluster, by stacking 70 Spitzer/IRAC frames at 3.6 and 4.5$\,μ…
A survey for variable young stars with small telescopes: VII -- Spot Properties on YSOs in IC5070
Carys Herbert, Dirk Froebrich, Aleks Scholz
We present measurements of spot properties on 31 young stellar objects, based on multi-band data from the HOYS (Hunting Outbursting Young Stars) project. On average the analysis fo…
Rogue planets and brown dwarfs: Predicting the populations of free-floating planetary mass objects observable with JWST
Aleks Scholz, Koraljka Muzic, Ray Jayawardhana +2
Free-floating (or rogue) planets are planets that are liberated (or ejected) from their host systems. Although simulations predict their existence in substantial numbers, direct ob…
Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars
M. Bonavita, C. Fontanive, R. Gratton +6
The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…
