TESS discovery of a super-Earth orbiting the M dwarf star TOI-1680
M. Ghachoui, A. Soubkiou, R. D. Wells +52
We report the discovery by the TESS mission of a super-Earth on a 4.8-d orbit around an inactive M4.5 dwarf (TOI-1680) validated by ground-based facilities. The host star is locate…
TOI-2084 b and TOI-4184 b: two new sub-Neptunes around M dwarf stars
K. Barkaoui, M. Timmermans, A. Soubkiou +67
We present the discovery and validation of two TESS exoplanets orbiting nearby M dwarfs: TOI-2084b, and TOI-4184b. We characterized the host stars by combining spectra from Shane/K…
The origin of the planetary nebula M 1-16. A morphokinematic and chemical analysis
M. A. Gómez-Muñoz, R. Vázquez, L. Sabin +4
We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a detailed morpho-kinemati…
Surface magnetism in the pulsating RV Tauri star R Scuti
Stefan Georgiev, Agnès Lèbre, Eric Josselin +3
We present the surface magnetic field conditions of the brightest pulsating RV Tauri star, R Sct. Our investigation is based on the longest spectropolarimetric survey ever performe…
Peering into the central region of a nano-quasar: XMM-Newton and Chandra views of the CH Cyg Symbiotic System
J. A. Toalá, O. González-Martín, M. Karovska +3
We present the analysis of archival XMM-Newton and Chandra observations of CH Cyg, one of the most studied symbiotic stars (SySts). The combination of the high-resolution XMM-Newto…
Three-dimensional orbit of AC Her determined: Binary-induced truncation cannot explain the large cavity in this post-AGB transition disk
Narsireddy Anugu, Jacques Kluska, Tyler Gardner +17
Some evolved binaries, namely post-asymptotic giant branch binaries, are surrounded by stable and massive circumbinary disks similar to protoplanetary disks found around young star…
