Status of the STUDIO UV balloon mission and platform
A. Pahler, M. Ångermann, J. Barnstedt +24
Stratospheric balloons offer accessible and affordable platforms for observations in atmosphere-constrained wavelength ranges. At the same time, they can serve as an effective step…
Microchannel-Plate Detector Development for Ultraviolet Missions
Lauro Conti, Jürgen Barnstedt, Sebastian Buntrock +19
The Institute for Astronomy and Astrophysics in Tübingen (IAAT) has a long-term experience in developing and building space-qualified imaging and photon counting microchannel-plate…
Mapping Diffuse Emission in Lyman UV band
Li Ji, Zheng Lou, Jinlong Zhang +38
The CAFE (Census of warm-hot intergalactic medium, Accretion, and Feedback Explorer) and LyRIC (Lyman UV Radiation from Interstellar medium and Circum-galactic medium) have been pr…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with TESS: I. Asteroseismology of the GW Vir stars RX J2117+3412, HS 2324+3944, NGC 6905, NGC 1501, NGC 2371, and K 1-16
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +7
In this paper, we present a detailed asteroseismological analysis of six GW Vir stars including the observations collected by the TESS mission. We processed and analyzed TESS obser…
An extremely hot white dwarf with a rapidly rotating K-type subgiant companion: UCAC2 46706450
Klaus Werner, Nicole Reindl, Lisa Löbling +5
UCAC2 46706450 is a late-type star with an ultraviolet (UV) excess. It was considered a candidate to establish a sample of FGK stars with white dwarf (WD) companions that can be us…
Graviballs and Dark Matter
B. Guiot, A. Borquez, A. Deur +1
We investigate the possible existence of graviballs, a system of bound gravitons, and show that two gravitons can be bound together by their gravitational interaction. This idea co…
