The sulphur species in hot rocky exoplanet atmospheres

L. J. Janssen, P. Woitke, O. Herbort +4

The first JWST observations of hot Jupiters showed an unexpected detection of SO2 in their hydrogen-rich atmospheres. We investigate how much sulphur can be expected in the atmosph…

Shape models and spin states of Jupiter Trojans: Testing the streaming instability formation scenario

Josef Hanuš, David Vokrouhlický, David Nesvorný +5

The leading theory for the origin of Jupiter Trojans (JTs) assumes that JTs were captured to their orbits near the Lagrangian points of Jupiter during the early reconfiguration of…

The influence of a static planetary atmosphere on spin transfer during pebble accretion

M. J. Yzer, R. G. Visser, C. Dominik

We study the effect an atmosphere has on pebble orbits and spin build-up on a planet's surface during pebble accretion in the extreme case of a static atmosphere. We numerically in…

Probing reflection from aerosols with the near-infrared dayside spectrum of WASP-80b

Bob Jacobs, Jean-Michel Désert, Peter Gao +9

The presence of aerosols is intimately linked to the global energy budget and the composition of a planet's atmospheres. Their ability to reflect incoming light prevents energy fro…

On wave interference in planet migration: dead zone torques modified by active zone forcing

R. O. Chametla, O. Chrenko, W. Lyra +1

We investigate planetary migration in the dead zone of a protoplanetary disk where there are a set of spiral waves propagating inward due to the turbulence in the active zone and t…

Expanding the inventory of spectral lines used to trace atmospheric escape in exoplanets

Dion Linssen, Antonija Oklopčić

Escaping exoplanet atmospheres have been observed as deep transit signatures in a few specific spectral lines. Detections have been made in the hydrogen Ly- line, the metastable…

TESS and CHEOPS Discover Two Warm Sub-Neptunes Transiting the Bright K-dwarf HD 15906

Amy Tuson, Didier Queloz, Hugh P. Osborn +119

We report the discovery of two warm sub-Neptunes transiting the bright (G = 9.5 mag) K-dwarf HD 15906 (TOI 461, TIC 4646810). This star was observed by the Transiting Exoplanet Sur…

Refined parameters of the HD 22946 planetary system and the true orbital period of planet d

Z. Garai, H. P. Osborn, D. Gandolfi +85

Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often escape detection. HD 22946 is…

Prediction of the collisions of meteoroids originating in comet 21P/Giacobini-Zinner with the Mercury, Venus, and Mars

Dušan Tomko, Luboš Neslušan

After the prediction of meteor showers in the Earth's atmosphere caused by the particles originating in the nucleus of comet 21P/Giacobini-Zinner, we went on with the prediction of…

Showers with both northern and southern solutions

L. Neslušan, T. J. Jopek, R. Rudawska +2

Meteoroids of a low-inclination stream hit the Earth arriving from a direction near the ecliptic. The radiant area of stream like this is often divided into two parts: one is situa…

Turbulent processing of PAHs in protoplanetary discs -- Coagulation and freeze-out leading to depletion of gas-phase PAH

K. Lange, C. Dominik, A. G. G. M. Tielens

Polycyclic aromatic hydrocarbons (PAHs) have been detected in numerous circumstellar discs. We propose the continuous processing of PAHs through clustering, adsorption on dust grai…
