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…
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…
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…
An absolute calibration of the near-infrared Period-Luminosity Relations of Type II Cepheids in the Milky Way and in the Large Magellanic Cloud
Piotr Wielgórski, Grzegorz Pietrzyński, Bogumił Pilecki +29
We present time-series photometry of 21 nearby Type II Cepheids in the near-infrared J, H and Ks passbands. We use this photometry, together with the Third Gaia Early Data Release…
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…
BRITE observations of Centauri and Lupi, the first non-eclipsing members of the new class of nascent binaries
M. Jerzykiewicz, A. Pigulski, G. Michalska +8
Results of an analysis of the BRITE-Constellation and SMEI photometry and radial-velocity observations, archival and new, of two single-lined spectroscopic binary systems Centa…
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…
Ensemble asteroseismology of pulsating B-type stars in NGC 6910
D. Moździerski, A. Pigulski, Z. Kołaczkowski +24
Asteroseismology offers the possibility of probing stellar interiors and testing evolutionary and seismic models. Precise photometry and spectroscopy obtained during multi-site cam…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
Variability survey in NGC 6910, the open cluster rich in Cephei-type stars
D. Moździerski, A. Pigulski, Z. Kołaczkowski +14
NGC 6910 is the northern hemisphere open cluster known to be rich in Cephei-type stars. Using four-season photometry obtained in Białków (Poland) and Xinglong (China) observato…
