A super-Earth and a sub-Neptune orbiting the bright, quiet M3 dwarf TOI-1266

open access: yes, 2021
© 2020 ESO. We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (K = 8.8), quiet, and nearby (37 pc) M3V dwarf TOI-1266.

An ultra-short-period transiting super-Earth orbiting the M3 dwarf TOI-1685

open access: yes, 2021
Dynamical histories of planetary systems, as well as the atmospheric evolution of highly irradiated planets, can be studied by characterizing the ultra-short-period planet population, which the TESS mission is particularly well suited to discover.

Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?

open access: yes, 2021
© ESO 2020. We report the confirmation of a transiting planet around the bright weakly active M0.5 V star TOI-1235 (TYC 4384-1735-1, V ≈ 11.5 mag), whose transit signal was detected in the photometric time series of sectors 14, 20, and 21 of the TESS ...

A multi-criteria assessment of deflection methods for dangerous NEOs [PDF]

open access: yes, 2007
Over the last few years, the possible scenario of an asteroid threatening to impact the Earth has stimulated an intense debate among the scientific community about possible deviation methods.

Planetary system around the nearby M dwarf GJ 357 including a transiting, hot, Earth-sized planet optimal for atmospheric characterization

open access: yes, 2020
We report the detection of a transiting Earth-size planet around GJ 357, a nearby M2.5 V star, using data from the Transiting Exoplanet Survey Satellite (TESS).

A multi-planetary system orbiting the early-M dwarf TOI-1238

open access: yes, 2023
Context. The number of super-Earth and Earth-mass planet discoveries has increased significantly in the last two decades thanks to the Doppler radial velocity and planetary transit observing techniques.

HD 23472: a multi-planetary system with three super-Earths and two potential super-Mercuries,

open access: yes, 2023
Context. Comparing the properties of planets orbiting the same host star, and thus formed from the same accretion disc, helps in constraining theories of exoplanet formation and evolution.

SmallSat interferometry for THz astrophysics

open access: yes, 2018
While great strides have been made in far-infrared astrophysics with the NASA Spitzer and ESA Herschel missions, subarcsecond spatial resolution from space is still beyond the reach of current technologies. The Atacama Large Millimeter Array has produced
