Transit timing and starspot-induced transit depth variations in the 17 Myr old HIP 67522 system
H. Chakraborty, M. Lendl, A. Nigioni +27
HIP 67522 is a one of the youngest multi-planetary systems discovered to date. The 17 Myr-old, Sun-like star is part of the Scorpius-Centarus OB association and is known to host tw…
Orbital motion and dynamical mass of the complex periodic variable binary system 2MASS J05082729-2101444
S. Curiel, G. N. Ortiz-León, V. J. S. Béjar +22
We used very long baseline interferometry to constrain the orbit of the binary system 2MASS J05082729-2101444. We observed the system with the VLBA in three epochs at a frequency o…
Occurrence rate of stellar Type II radio bursts from a 100 star-year search for coronal mass ejections
David C. Konijn, Harish K. Vedantham, Cyril Tasse +8
Coronal mass ejections (CMEs) are major drivers of space weather in the Solar System, but their occurrence rate on other stars is unknown. A characteristic (deca-)metric radio burs…
Polarized, variable radio emission from the scallop-shell binary system DG CVn
Simranpreet Kaur, Daniele Viganò, Jackie Villadsen +9
DG CVn is an eruptive variable star and represents the closest member of the known sample of complex periodic variables, or scallop-shell stars. Over the years, this M dwarf binary…
