TT Arietis: New approach to the analysis of quasi-periodic oscillations

I. Vega-Manubens, N. Vogt, A. Lopera-Mejía +2

Context. TT Arietis (TT Ari) is a nova-like cataclysmic variable of the VY Scl subtype with light-curve variations on multiple timescales. In addition to the superhump modulation,…

The eclipse of the V773 Tau B circumbinary disk

M. A. Kenworthy, D. González Picos, E. Elizondo +9

A deep (~70%) and extended (~150 days) eclipse was seen towards the young multiple stellar system V773 Tau in 2010. We interpret it as due to the passage of a circumbinary disk aro…

A Search for recurrent novae among Far Eastern guest stars

Susanne M Hoffmann, Nikolaus Vogt

According to recent theoretical studies, classical novae are expected to erupt every ~ years, while the recurrence time scale of modern recurrent novae (N_r) stars ranges fro…

Discovery of a directly imaged planet to the young solar analog YSES 2

Alexander J. Bohn, Christian Ginski, Matthew A. Kenworthy +8

Abbreviated. By selecting stars with similar ages and masses, the Young Suns Exoplanet Survey (YSES) aims to detect and characterize planetary-mass companions to solar-type host st…

How many suns are in the sky? A SPHERE multiplicity survey of exoplanet host stars I -- Four new close stellar companions including a white dwarf

Christian Ginski, Markus Mugrauer, Christian Adam +2

We are studying the influence of stellar multiplicity on exoplanet systems, in particular systems that have been detected via radial-velocity searches. We are in particular interes…

A Search for the modern counterparts of the Far Eastern guest stars 369 CE, 386 CE, and 393 CE

Susanne M Hoffmann, Nikolaus Vogt

In this study, we apply our previously developed method to investigate ancient transient sightings in order to derive consequences for modern astrophysical problems.We present case…
