Shape Analysis of HII Regions -- II. Synthetic Observations
Justyn Campbell-White, Ahmad A. Ali, Dirk Froebrich +1
The statistical shape analysis method developed for probing the link between physical parameters and morphologies of Galactic HII regions is applied here to a set of synthetic obse…
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…
Planetary Nebulae in the UWISH2 survey
T. M. Gledhill, D. Froebrich, J. Campbell-White +1
Near-infrared imaging in the 1 - 0 S(1) emission line of molecular hydrogen is able to detect planetary nebulae (PNe) that are hidden from optical emission line surveys. We present…
A survey for variable young stars with small telescopes: First results from HOYS-CAPS
D. Froebrich, J. Campbell-White, A. Scholz +15
Variability in Young Stellar Objects (YSOs) is one of their primary characteristics. Long-term, multi-filter, high-cadence monitoring of large YSO samples is the key to understand…
Shape Analysis of HII Regions - I. Statistical Clustering
Justyn Campbell-White, Dirk Froebrich, Alfred Kume
We present here our shape analysis method for a sample of 76 Galactic HII regions from MAGPIS 1.4 GHz data. The main goal is to determine whether physical properties and initial co…
