Everything that glitters is not gold: V1315 Cas is not a dormant black hole
J. Zak, D. Jones, H. M. J. Boffin +11
The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass invisible companion and…
A detailed study of the barium central star of the planetary nebula Abell 70
David Jones, Henri M. J. Boffin, Alex J. Brown +4
We present a detailed study of the barium star at the heart of the planetary nebula Abell 70. Time-series photometry obtained over a period of more than ten years demonstrates that…
The post-common-envelope binary central star of the planetary nebula Ou 5: a doubly-eclipsing post-red-giant-branch system
David Jones, James Munday, Romano Corradi +10
We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou~5. Low-resolution spectra obtained duri…
A tidally tilted sectoral dipole pulsation mode in the eclipsing binary TIC 63328020
S. A. Rappaport, D. W. Kurtz, G. Handler +13
We report the discovery of the third tidally tilted pulsator, TIC 63328020. Observations with the TESS satellite reveal binary eclipses with an orbital period of 1.1057 d, and …
Ondr}ejov echelle spectrograph, ground based support facility for exoplanet missions
Petr Kabath, Marek Skarka, Silvia Sabotta +18
Fulfilling the goals of space-based exoplanetary transit surveys, like Kepler and TESS, is impossible without ground-based spectroscopic follow-up. In particular, the first-step ve…
High-resolution transmission spectroscopy of four hot inflated gas giant exoplanets
Jiri Zak, Petr Kabath, Henri M. J. Boffin +2
The technique of transmission spectroscopy allows us to constrain the chemical composition of the atmospheres of transiting exoplanets. It relies on very high signal-to-noise spect…
Detection limits of exoplanetary atmospheres with 2-m class telescopes
P. Kabath, J. Zak, H. M. J. Boffin +3
Transmission spectroscopy is an important technique to probe the atmospheres of exoplanets. With the advent of TESS and, in the future, of PLATO, more and more transiting planets a…
