We write to report the discovery that Deneb is a large-amplitude polarization variable. Over a ∼400 days time span from 2022 August Deneb’s polarization was typically around 3900 parts per million (ppm) in the SDSS ${g}^{{\prime} }$ band. Yet, it

KIC 7955301 is a hierarchical triple system with eclipse timing and depth variations discovered by the Kepler mission. It is composed of a non-eclipsing primary star at the bottom of the red giant branch on a 209-day orbit with a K/G-type main-sequen

In asteroseismology, the surface effect refers to a disparity between the observed and the modelled frequencies in stars with solar-like oscillations. It originates from improper modelling of the surface layers. Correcting the surface effect usually

Is there something distinctive about mobilities research being carried out in the Southern Hemisphere? This question arose in the course of a conversation I had with Professor Gordon Pirie over lunch at the Berlin Transport Museum, during the inaugur
