Circalunar variations of the night sky brightness -- an FFT perspective on the impact of light pollution
Johannes Puschnig, Stefan Wallner, Thomas Posch
Circa-monthly activity conducted by moonlight is observed in many species on Earth. Given the vast amount of artificial light at night (ALAN) that pollutes large areas around the g…
Systematic measurements of the night sky brightness at 26 locations in Eastern Austria
Thomas Posch, Franz Binder, Johannes Puschnig
We present an analysis of the zenithal night sky brightness (henceforth: NSB) measurements at 26 locations in Eastern Austria focussing on the years 2015-2016, both during clear an…
Measuring night sky brightness: methods and challenges
Andreas Hänel, Thomas Posch, Salvador J. Ribas +10
Measuring the brightness of the night sky has become an increasingly important topic in recent years, as artificial lights and their scattering by the Earths atmosphere continue sp…
Dusty shells surrounding the carbon variables S Scuti and RT Capricorni
M. Mecina, F. Kerschbaum, M. A. T. Groenewegen +8
For the Mass-loss of Evolved StarS (MESS) programme, the unprecedented spatial resolution of the PACS photometer on board the Herschel space observatory was employed to map the dus…
Herschel/PACS observations of the 69 band of crystalline olivine around evolved stars
J. A. D. L. Blommaert, B. L. de Vries, L. B. F. M. Waters +15
We present 48 Herschel/PACS spectra of evolved stars in the wavelength range of 67-72 m. This wavelength range covers the 69 m band of crystalline olivine ($\text{Mg}_{2-2x}\…
The wind of W Hya as seen by Herschel - I. The CO envelope
T. Khouri, A. de Koter, L. Decin +25
Asymptotic giant branch (AGB) stars lose their envelopes by means of a stellar wind whose driving mechanism is not understood well. Characterizing the composition and thermal and d…
