Astronomy from the moon in the next decades: from exoplanets to cosmology in visible light and beyond [PDF]
We look at what astronomy from the Moon might be like over the next few decades. The Moon offers the possibility of installing large telescopes or interferometers with instruments larger than those on orbiting telescopes. We first present examples of ambitious science cases, in particular ideas that cannot be implemented from Earth.

Astronomy First direct detection of an exoplanet by optical interferometry Astrometry and K -band spectroscopy of HR 8799 e [PDF]
Aims. To date, infrared interferometry at best achieved contrast ratios of a few times 10−4 on bright targets. GRAVITY, with its dual-field mode, is now capable of high contrast observations, enabling the direct observation of exoplanets. We demonstrate the technique on HR 8799, a young planetary system composed of four known giant exoplanets. Methods.

Exoplanet Research with the Stratospheric Observatory for Infrared Astronomy (SOFIA) [PDF]
When the Stratospheric Observatory for Infrared Astronomy (SOFIA) was conceived and its first science cases defined, exoplanets had not been detected. Later studies, however, showed that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and eclipses are feasible with SOFIA's instrumentation ...

Classification of Trajectories in a Two-planet Exosystem Using the Generalized Three-body Problem
We deploy the theory of the generalized three-body problem to describe an exosystem composed of a host star, a transiting Jupiter-sized exoplanet, and an Earth-sized exoplanet.

A microlensing event is mainly used to search for free-floating planets (FFPs). To estimate the FFP mass and distance via the microlensing effect, a microlensing parallax is one of the key parameters.

Fizzy Super-Earths: Impacts of Magma Composition on the Bulk Density and Structure of Lava Worlds
Lava worlds are a potential emerging population of Super-Earths that are on close-in orbits around their host stars, with likely partially molten mantles. To date, few studies have addressed the impact of magma on the observed properties of a planet.

Classify and Explore the Diversity of Planetary Population and Interior Properties
Classification is an essential method and has been developed widely in astronomy. However, planets still lack a universal classification framework, because the solar system planet sample is too small for statistical analysis.
