Chaotic dynamics in the pulsation of DF Cygni, as observed by Kepler
E. Plachy, A. Bódi, Z. Kolláth
Pulsations of RV Tauri-type variable stars can be governed by chaotic dynamics. However, observational evidence for this happening is usually hard to come by. Here we use the conti…
Tracking the dynamics of skyglow with differential photometry using a digital camera with fisheye lens
Andreas Jechow, Salvador J. Ribas, Ramon Canal-Domingo +3
Artificial skyglow is dynamic due to changing atmospheric conditions and the switching on and off of artificial lights throughout the night. Street lights as well as the ornamental…
Night sky quality monitoring in existing and planned dark sky parks by digital cameras
Zoltán Kolláth, Anita Dömény
A crucial part of the qualification of international dark sky places (IDSPs) is the objective measurement of night time sky luminance or radiance. Modern digital cameras provide an…
Measuring Light Pollution with Fisheye Lens Imagery from A Moving Boat, A Proof of Concept
Andreas Jechow, Zoltán Kolláth, Amit Lerner +4
Near all-sky imaging photometry was performed from a boat on the Gulf of Aqaba to measure the night sky brightness in a coastal environment. The boat was not anchored, and therefor…
Magnetic cycles at different ages of stars
K. Oláh, Zs. Kővári, K. Petrovay +4
We study the different patterns of interannual magnetic variability in stars on or near the lower main sequence, approximately solar-type (G-K dwarf) stars in time series of 36 yea…
Evaluating the summer night sky brightness at a research field site on Lake Stechlin in northeastern Germany
Andreas Jechow, Franz Hölker, Zoltán Kolláth +2
We report on luminance measurements of the summer night sky at a field site on a freshwater lake in northeastern Germany (Lake Stechlin) to evaluate the amount of artificial skyglo…
