A survey for variable young stars with small telescopes: IV -- Rotation Periods of YSOs in IC5070

Dirk Froebrich, Efthymia Derezea, Aleks Scholz +50

Studying rotational variability of young stars is enabling us to investigate a multitude of properties of young star-disk systems. We utilise high cadence, multi-wavelength optical…

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…

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: VI -- Analysis of the outbursting Be stars NSW284, Gaia19eyy, and VES263

Dirk Froebrich, Lynne A. Hillenbrand, Carys Herbert +44

This paper is one in a series reporting results from small telescope observations of variable young stars. Here, we study the repeating outbursts of three likely Be stars based on…

A survey for variable young stars with small telescopes: II -- Mapping a protoplanetary disk with stable structures at 0.15 AU

Jack J. Evitts, Dirk Froebrich, Aleks Scholz +57

The HOYS citizen science project conducts long term, multifilter, high cadence monitoring of large YSO samples with a wide variety of professional and amateur telescopes. We presen…
