Near-infrared and optical emission of WASP-5 b

Search for giant planets around seven white dwarfs in the Hyades cluster with the Hubble Space Telescope
(Oxford University Press, 2021-01-01)
Only a small number of exoplanets have been identified in stellar cluster environments. We initiated a high angular resolution direct imaging search using the Hubble Space Telescope (HST) and its Near-Infrared Camera and ...
Formation of short-period planets by disc migration
(2019-01-01)
Protoplanetary discs are thought to be truncated at orbital periods of around 10 d. Therefore, the origin of rocky short-period planets with P < 10 d is a puzzle. We propose that many of these planets may form through the ...
HD 207897 b: A dense sub-Neptune transiting a nearby and bright K-type star

Formation of planetary systems by pebble accretion and migration: Hot super-Earth systems from breaking compact resonant chains
(2021-06-01)
At least 30% of main sequence stars host planets with sizes of between 1 and 4 Earth radii and orbital periods of less than 100 days.We use N-body simulations including a model for gas-assisted pebble accretion and disk–planet ...
Observability of planet-disc interactions in CO kinematics
(Oxford University Press, 2018)
Empirical evidence of planets in gas-rich circumstellar discs is required to constrain giant planet formation theories. Here we study the kinematic patterns which arise from planet- disc interactions and their observability ...
