Chamaeleon DANCe. Revisiting the stellar populations of Chamaeleon I and Chamaeleon II with Gaia-DR2 data
P. A. B. Galli, H. Bouy, J. Olivares +6
Context: Chamaeleon is the southernmost low-mass star-forming complex within 200 pc from the Sun. Its stellar population has been extensively studied in the past, but the current c…
Even More Rapidly Rotating Pre-Main Sequence M Dwarfs with Highly Structured Light Curves: An Initial Survey in the Lower Centaurus-Crux and Upper Centaurus-Lupus Associations
J. R. Stauffer, L. M. Rebull, M. Jardine +6
Using K2, we recently discovered a new type of periodic photometric variability while analysing the light curves of members of Upper Sco (Stauffer \etal\ 2017). The 23 exemplars of…
The Magellan-TESS Survey I: Survey Description and Mid-Survey Results
Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66
revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…
Planetary system LHS 1140 revisited with ESPRESSO and TESS
J. Lillo-Box, P. Figueira, A. Leleu +17
LHS 1140 is an M dwarf known to host two known transiting planets at orbital periods of 3.77 and 24.7 days. The external planet (LHS 1140 b) is a rocky super-Earth that is located…
Lupus DANCe. Census of stars and 6D structure with Gaia-DR2 data
P. A. B. Galli, H. Bouy, J. Olivares +8
Context: Lupus is recognised as one of the closest star-forming regions, but the lack of trigonometric parallaxes in the pre-Gaia era hampered many studies on the kinematic propert…
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…
