Planetary systems in the light of asteroseismology: metallicity threshold for the planetary systems and age-metallicity relation

M. Yıldız, A. Demirkol, S. Örtel +2

We compiled data for 127 hosts (plus six candidates) and used them as constraints to construct interior models of the hosts using the {\small MESA} code. Two significant conclusion…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…

The Roman View of Strong Gravitational Lenses

Bryce Wedig, Tansu Daylan, Simon Birrer +13

Galaxy-galaxy strong gravitational lenses can constrain dark matter models and the Lambda Cold Dark Matter cosmological paradigm at sub-galactic scales. Currently, there is a deart…

Strong gravitational lenses from the Vera C. Rubin Observatory

Anowar J. Shajib, Graham P. Smith, Simon Birrer +6

Like many areas of astrophysics and cosmology, the Vera C. Rubin Observatory will be transformational for almost all the applications of strong lensing, thanks to the dramatic incr…

Two Earth-size Planets and an Earth-size Candidate Transiting the Nearby Star HD 101581

Michelle Kunimoto, Zifan Lin, Sarah Millholland +43

We report the validation of multiple planets transiting the nearby ( pc) K5V dwarf HD 101581 (GJ 435, TOI-6276, TIC 397362481). The system consists of at least two Earth-…
