The Roman Coronagraph Community Participation Program: early calibration plan and pilot observation of a companion

Julien H. Girard, Eric Cady, Neil T. Zimmerman +42

Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…

ANDES, the high-resolution spectrograph of the ELT: simulated performance of the CORO module and overview of the high-contrast capabilities for exoplanet observations

M. N'Diaye, A. Simonnin, A. Spang +19

We present the simulated performance of the coronagraph (CORO) module for ANDES, the Extremely Large Telescope (ELT) high-resolution spectrograph. ANDES aims to address a broad ran…

ngVLTI: Cost and Feasibility of a Four-Telescope VLTI Expansion for Milliarcsecond-Scale Imaging

Sylvestre Lacour, Johan Kosmalski, Michael Mueller +8

We assess the cost and technical feasibility of extending the Very Large Telescope Interferometer (VLTI) through the addition of four 8 m-class Unit Telescopes (UTs), an upgrade we…

Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources

T. Cavalié, R. Moreno, C. Lefour +16

Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. This work aims…

Exoplanets in reflected starlight with dual-field interferometry: A case for shorter wavelengths and a fifth Unit Telescope at VLTI/Paranal

S. Lacour, Ó. Carrión-González, M. Nowak

The direct observation of cold and temperate planets within 1 to 10 AU would be extremely valuable for uncovering their atmospheric compositions but remains a formidable challenge…

Radiative-convective models of the atmospheres of Uranus and Neptune: heating sources and seasonal effects

G. Milcareck, S. Guerlet, F. Montmessin +10

The observations made during the Voyager 2 flyby have shown that the stratosphere of Uranus and Neptune are warmer than expected by previous models. In addition, no seasonal variab…

A 3D picture of moist-convection inhibition in hydrogen-rich atmospheres: Implications for K2-18 b

Jérémy Leconte, Aymeric Spiga, Noé Clément +9

While small, Neptune-like planets are among the most abundant exoplanets, our understanding of their atmospheric structure and dynamics remains sparse. In particular, many unknowns…

Doppler wind measurements in Neptune's stratosphere with ALMA

Óscar Carrión-González, Raphael Moreno, Emmanuel Lellouch +6

Neptune's tropospheric winds are among the most intense in the Solar System, but the dynamical mechanisms that produce them remain uncertain. Measuring wind speeds at different pre…

Possible Atmospheric Diversity of Low Mass Exoplanets, some Central Aspects

John Lee Grenfell, Jeremy Leconte, François Forget +9

Exoplanetary science continues to excite and surprise with its rich diversity. We discuss here some key aspects potentially influencing the range of exoplanetary terrestrial-type a…
