An Ultra-Short Period Super-Earth and a Sub-Neptune Orbiting the K dwarf TOI-4311
Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrew Collier Cameron +95
We report the discovery and characterisation of the multi-planetary system around TOI-4311, a K dwarf kinematically between the Galactic thick disk and Hercules stream. TOI-4311 ho…
Close-in faint companions mimicking interferometric hot exozodiacal dust observations
Katsiaryna Tsishchankava, Florian Kirchschlager, Anton Krieger +2
Context: Interferometric observations of various nearby main-sequence stars show an unexpected infrared excess, raising the question of its origin. The two dominant interpretations…
Hot exozodiacal dust around Fomalhaut: The MATISSE perspective
Kevin Ollmann, Florian Kirchschlager, Thomas A. Stuber +6
Excess over the stellar photospheric emission of main-sequence stars has been found in interferometric near-infrared observations, and is attributed to the presence of hot exozodia…
Improving Monte Carlo radiative transfer simulations: A shift of framework
Anton Krieger, Sebastian Wolf
Monte Carlo radiative transfer (MCRT) simulations are a powerful tool for determining the appearance of astrophysical objects, analyzing the prevalent physical conditions within th…
