The 2014-2017 outburst of the young star ASASSN-13db: A time-resolved picture of a very low-mass star between EXors and FUors
A. Sicilia-Aguilar, A. Oprandi, D. Froebrich +13
ASASSN-13db is a M5-type star with a protoplanetary disk, the lowest mass star known to experience accretion outbursts. Since its discovery in 2013, it has experienced two outburst…
Long-term variability of T Tauri stars using WASP
Laura Rigon, Aleks Scholz, David Anderson +1
We present a reference study of the long-term optical variability of young stars using data from the WASP project. Our primary sample is a group of well-studied classical T Tauri s…
Variability in young very low mass stars: Two surprises from spectrophotometric monitoring
I. Bozhinova, A. Scholz, J. Eislöffel
We present simultaneous photometric and spectroscopic observations of seven young and highly variable M dwarfs in star forming regions in Orion, conducted in 4 observing nights wit…
The young low-mass star ISO-Oph-50: Extreme variability induced by a clumpy, evolving circumstellar disk
Aleks Scholz, Koraljka Muzic, Vincent Geers
ISO-Oph-50 is a young low-mass object in the ~Myr old Ophiuchus star forming region undergoing dramatic changes in its optical/near/mid-infrared brightness by 2-4 mag. We present n…
Near Infrared Spectroscopy of Young Brown Dwarfs in Upper Scorpius
P. Dawson, A. Scholz, T. P. Ray +3
Spectroscopic follow-up is a pre-requisite for studies of the formation and early evolution of brown dwarfs. Here we present IRTF/SpeX near-infrared spectroscopy of 30 candidate me…
Planetary host stars: Evaluating uncertainties in ultra-cool model atmospheres
I. Bozhinova, Ch. Helling, A. Scholz
M-dwarfs are emerging in the literature as promising targets for detecting low-mass, Earth-like planets. An important step in this process is to determine the stellar parameters of…
The main-sequence rotation-colour relation in the Coma Berenices open cluster
A. Collier Cameron, V. A. Davidson, L. Hebb +24
We present the results of a photometric survey of rotation rates in the Coma Berenices (Melotte 111) open cluster, using data obtained as part of the SuperWASP exoplanetary transit…
A Chandra and Spitzer census of the young star cluster in the reflection nebula NGC 7129
B. Stelzer, A. Scholz
The reflection nebula NGC 7129 has long been known to be a site of recent star formation as evidenced, e.g., by the presence of deeply embedded protostars and HH objects. However,…
