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…
Original Research By Young Twinkle Students (ORBYTS): Ephemeris Refinement of Transiting Exoplanets
Billy Edwards, Quentin Changeat, Kai Hou Yip +60
We report follow-up observations of transiting exoplanets that have either large uncertainties (>10 minutes) in their transit times or have not been observed for over three years.…
ExoClock Project: An open platform for monitoring the ephemerides of Ariel targets with contributions from the public
Anastasia Kokori, Angelos Tsiaras, Billy Edwards +46
The Ariel mission will observe spectroscopically around 1000 exoplanets to further characterise their atmospheres. For the mission to be as efficient as possible, a good knowledge…
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: 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…
TrES-1 b: A Case Study in Detecting Secular Evolution of Exoplanet Orbits
Simone R. Hagey, Billy Edwards, Angelos Tsiaras +43
We present a comprehensive analysis of transit, eclipse, and radial velocity data of the hot Jupiter TrES-1 b and confirm evidence of orbital variations on secular timescales. Appa…
