Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake. How do Planetary Systems Form?

I. Mendigutía, N. Huélamo, I. Jiménez-Serra +32

The detection and characterization of protoplanets in protoplanetary disks around young stars is emerging as a transformative field that will redefine our understanding of how plan…

Giant Outer Transiting Exoplanet Mass (GOTEM) Survey.VII. TOI-6041: a multi-planet system including a warm Neptune exhibiting strong TTVs

N. Heidari, A. Alnajjarine, H. P. Osborn +101

We present the characterization of the TOI-6041 system, a bright () G7-type star hosting at least two planets. The inner planet, TOI-6041b, is a warm Neptune wit…

HARPS-N, TESS, and CHEOPS discover a transiting sub-Neptune and two outer companions around the bright solar analogue HD 85426

F. Lienhard, A. Mortier, A. Collier Cameron +96

We provide a detailed characterisation of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99 ; : 1.13 $\text{R…

Disk fraction among free-floating planetary-mass objects in Upper Scorpius

Tommy Rodrigues, Hervé Bouy, Sean N. Raymond +9

Free-floating planetary-mass objects (FFPs) have been detected through direct imaging in several young, nearby star-forming regions. The properties of circumstellar disks around th…

Transit Timing Variations in HIP 41378: CHEOPS and TESS confirm a non-transiting sixth planet in the system

P. Leonardi, L. Borsato, L. Pagliaro +89

In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are…

An Ultra-Short Period Super-Earth and Sub-Neptune Spanning the Radius Valley Orbiting the Kinematic Thick Disk Star TOI-2345

Yoshi Nike Emilia Eschen, Thomas G. Wilson, Andrea Bonfanti +94

A crucial chemical link between stars and their orbiting exoplanets is thought to exist. If universal, this connection could affect the formation and evolution of all planets. Ther…
