A survey for variable young stars with small telescopes - XI. Spot Lifetimes and Coverage Distributions
Dirk Froebrich, Carys Herbert, Aleks Scholz +47
We present a homogeneous analysis of rotational variability and spot properties in young stellar objects across multiple star-forming regions observed by the Hunting Outbursting Yo…
Hubble's Variable Nebula I: Ripples on a Big Screen
John Lightfoot, Aleks Scholz
NGC2261 is a reflection nebula illuminated by the young star R Monocerotis. Objects moving near the star occasionally cast shadows on the nebula, giving rise to its alternative nam…
Disks around young free-floating planetary-mass objects: Ultradeep Spitzer imaging of IC348
Holly Hanbee Seo, Aleks Scholz
Protoplanetary disks have been found around free-floating objects with masses comparable to those of giant planets. The frequency and properties of these disks around planetary-mas…
A survey for variable stars with small telescopes: IX -- Evolution of Spot Properties on YSOs in IC5070
Carys Herbert, Dirk Froebrich, Siegfried Vanaverbeke +45
We present spot properties on 32 periodic young stellar objects in IC 5070. Long term, 5 yr, light curves in the , , and -bands are obtained through the HOYS (Huntin…
A survey for variable young stars with small telescopes: VIII -- Properties of 1687 Gaia selected members in 21 nearby clusters
Dirk Froebrich, Aleks Scholz, Justyn Campbell-White +60
The Hunting Outbursting Young Stars (HOYS) project performs long-term, optical, multi-filter, high cadence monitoring of 25 nearby young clusters and star forming regions. Utilisin…
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Westerlund 1 and 2 Open Clusters Survey
M. G. Guarcello, E. Flaccomio, J. F. Albacete-Colombo +48
Context. With a mass exceeding several 10^4 solar masses and a rich and dense population of massive stars, supermassive young star clusters represent the most massive star-forming…
Relation of X-ray activity and rotation in M dwarfs and predicted time-evolution of the X-ray luminosity
E. Magaudda, B. Stelzer, K. R. Covey +3
We present a sample of 14 M dwarf stars observed with XMM-Newton and Chandra, for which we also computed rotational periods from Kepler Two-Wheel (K2) Mission light curves. We comp…
The enigmatic young brown dwarf binary FU Tau: accretion and activity
B. Stelzer, A. Scholz, C. Argiroffi +1
FU Tau belongs to a rare class of young, wide brown dwarf binaries. We have resolved the system in a Chandra X-ray observation and detected only the primary, FU Tau A. Hard X-ray e…
