Physical conditions of gas components in debris disks of 49 Ceti and HD 21997
Aya E. Higuchi, Ágnes Kóspál, Attila Moór +2
Characterization of gas component in debris disks is of fundamental importance for understanding its origin. Toward this goal, we have conducted non-LTE (local thermodynamic equili…
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs
F. L. Rommel, F. Braga-Ribas, J. Desmars +66
Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Ste…
ALMA and VLA Observations of EX Lupi in its Quiescent State
Jacob Aaron White, Á. Kóspál, A. G. Hughes +15
Extreme outbursts in young stars may be a common stage of pre-main-sequence stellar evolution. These outbursts, caused by enhanced accretion and accompanied by increased luminosity…
The hot dayside and asymmetric transit of WASP-189b seen by CHEOPS
M. Lendl, Sz. Csizmadia, A. Deline +102
The CHEOPS space mission dedicated to exoplanet follow-up was launched in December 2019, equipped with the capacity to perform photometric measurements at the 20 ppm level. As CHEO…
An update to the MARVEL dataset and ExoMol line list for 12C2
Laura K. McKemmish, Anna-Maree Syme, Jasmin Borsovszky +4
The spectrum of dicarbon (C2) is important in astrophysics and for spectroscopic studies of plasmas and flames. The C2 spectrum is characterized by many band systems with new ones…
Herschel-PACS photometry of Uranus' five major moons
Ö. H. Detre, T. G. Müller, U. Klaas +3
Aims. We aim to determine far-infrared fluxes at 70, 100, and 160m of the five major Uranus satellites Titania, Oberon, Umbriel, Ariel and Miranda, based on observations with th…
A new perturbative solution to the motion around triangular Lagrangian points in the elliptic restricted three-body problem
B. Boldizsár, T. Kovács, J. Vanyó
The equations of motion of planar elliptic restricted three body problem are transformed to four decoupled Hill's equations. By using the Floquet theorem analytic solution to the o…
Dynamics of spherical space debris of different sizes falling to Earth
Judit Slíz-Balogh, Dániel Horváth, Róbert Szabó +1
Space debris larger than 1 cm can damage space instruments and impact Earth. The low-Earth orbits (at heights smaller than 2000 km) and orbits near the geostationary- Earth orbit (…
Cold, dry, windy, and UV irradiated -- surveying Mars relevant conditions in Ojos del Salado Volcano (Andes Mountains, Chile)
Á. Kereszturi, J. Aszalós, Zs. Heiling +8
The Special Collection of papers in this issue of Astrobiology provide an overview of the characteristics and potential for future exploration of the Ojos del Salado volcano, locat…
Role of spectral resolution for infrared asteroid compositional analysis using meteorite spectra
A. Skulteti, A. Kereszturi, Zs. Kereszty +3
In this work the potential mineral identification of meteorites is analysed for the mid-infrared range, to evaluate observational possibilities for future missions targeting small…
