PRODIGE - envelope to disk with NOEMA III. The origin of complex organic molecule emission in SVS13A
(EDP Sciences, 2024)Complex organic molecules (COMs) have been found toward low-mass protostars, but the origins of the COM emission are still unclear. It can be associated with, for example, hot corinos, outflows, and/or accretion shock and ... -
Stellar companions and Jupiter-like planets in young associations
(EDP Sciences, 2024)Context. The formation mechanisms of stellar, brown dwarf, and planetary companions, their dependencies on the environment and their interactions with each other are still not well established. Recently, combining ... -
The polarisation properties of the HD 181327 debris ring. Evidence for sub-micron particles from scattered light observations
(EDP Sciences, 1 March 2024)Context. Polarisation is a powerful remote-sensing tool to study the nature of particles scattering the starlight. It is widely used to characterise interplanetary dust particles in the Solar System and increasingly employed ... -
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems. IV. NIRISS Aperture Masking Interferometry Performance and Lessons Learned
(American Astronomical Society / IOP Publishing, 19 February 2024)We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS). Thanks to self-calibrating observables, ... -
Implications of the discovery of AF Lep b. The mass-luminosity relation for planets in the β Pic Moving Group and the L–T transition for young companions and free-floating planets
(EDP Sciences, 5 April 2024)Context. Dynamical masses of young planets aged between 10 and 200 Myr detected in imaging play a crucial role in shaping models of giant planet formation. Regrettably, only a few such objects possess these characteristics. ...
