The impact of electron precipitation on Earth's thermospheric NO production and the drag of LEO satellites

M. Scherf, S. Krauss, G. Tsurikov +6

We investigate the response of space weather events on Earth's upper atmosphere over the polar regions by studying their effect on the drag of the CHAMP and GRACE satellites. Incre…

MINDS: The molecule-rich disc of the Herbig star HD 35929 revealed with JWST/MIRI

Till Kaeufer, Rens Waters, Danny Gasman +16

Our knowledge of the chemical composition of the gas in the inner disc of intermediate-mass young stars is limited, due to the lack of suitable instrumentation. The launch of JWST…

Transit-timing variations in the AU Mic system observed with CHEOPS

Á. Boldog, Gy. M. Szabó, L. Kriskovics +86

AU Mic is a very active M dwarf with an edge-on debris disk and two transiting sub-Neptunes with a possible third planetary companion. The two transiting planets exhibit significan…

Detection of the tidal deformation of WASP-103b at with CHEOPS

S. C. C. Barros, B. Akinsanm, G. Boué +5

WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral-in times. Measuring the tidal deformat…

The young Sun's XUV-activity as a constraint for lower CO-limits in the Earth's Archean atmosphere

C. P. Johnstone, H. Lammer, K. G. Kislyakova +2

Despite their importance for determining the evolution of the Earth's atmosphere and surface conditions, the evolutionary histories of the Earth's atmospheric CO abundance duri…

Feedback of molecular outflows from protostars in NGC 1333, revealed by Herschel and Spitzer spectro-imaging observations

Odysseas Dionatos, Lars. E. Kristensen, Mario Tafalla +2

Large scale spectral maps of star forming regions enable the comparative study of the gas excitation around an ensemble of sources at a common frame of reference, providing direct…
