WALTzER: Wide-band Atmospheric Laboratory for Transiting Exoplanet Research

A. G. Sreejith, L. Fossati, M. Lendl +81

Understanding the origin and evolution of planetary atmospheres, and the connection between their lower and upper atmospheric layers, remains a fundamental challenge in exoplanet s…

Aligned, Misaligned and Polar Orbits of Hot Jupiters: Measuring Spin-Orbit Angles via Doppler Tomography with HARPS-N

Z. Balkóová, J. Žák, M. Skarka +4

Although the migration of hot Jupiters is not yet fully understood, measurements of the projected spin-orbit angle λ help shed light on the processes involved. Here we present Dopp…

Resolving Galaxy Nuclei and Compact Stellar Systems as Engines of Galaxy Evolution

Julia Lamprecht, Izzy L. Garland, Daniel Jadlovsky +2

In this white paper we focus on compact stellar systems, star clusters, nuclear star clusters (NSCs), stripped nuclei, and ultra-compact dwarfs (UCDs), as engines of galaxy evoluti…

ExoNAMD: Leveraging the spin-orbit angle to constrain the dynamics of multiplanetary systems

A. Bocchieri, J. Zak, D. Turrini

Multiplanetary systems are excellent laboratories for studying the formation and evolution of exoplanets inside the same stellar environment. The number of known multiplanetary sys…

The evolution of PUCHEROS from a basic to a competitive tool for stellar astrophysics

Luca Antonucci, Leonardo Vanzi, Abner Zapata +16

We present PUCHEROS +, a new spectrograph developed as an enhanced version of PUCHEROS (Pontificia Universidad Catolica High Echelle Resolution Optical Spectrograph), which was the…

PLATOSpec: a precise spectrograph in support of space missions

P. Kabáth, M. Skarka, A. Hatzes +42

The upcoming space missions that will characterize exoplanets, such as PLATO and Ariel, will collect huge amounts of data that will need to be complemented with ground-based observ…

On the synergetic use of Ariel and JWST for exoplanet atmospheric science

Quentin Changeat, Pierre-Olivier Lagage, Giovanna Tinetti +27

This paper explores the potential for strategic synergies between the JWST and the Ariel telescopes, two flagship observatories poised to revolutionise the study of exoplanet atmos…

PLATOSpec's first results: planets WASP-35b and TOI-622b are on aligned orbits, and K2-237b is on a polar orbit

J. Zak, P. Kabath, H. M. J. Boffin +10

The spin-orbit angle between a stellar spin axis and its planetary orbital axis is a key diagnostic of planetary migration pathways, yet the mechanisms shaping the observed spin-or…

Ten Aligned Orbits: Planet Migration in the Era of JWST and Ariel

J. Zak, H. M. J. Boffin, A. Bocchieri +3

Understanding the diverse formation and migration pathways that shape exoplanetary systems requires characterizing both their atmospheric properties and their orbital dynamics. A k…

Stellar obliquities of eight close-in gas giant exoplanets

J. Zak, H. M. J. Boffin, E. Sedaghati +4

The Rossiter-McLaughlin effect allows us to measure the projected stellar obliquity of exoplanets. From the spin-orbit alignment, planet formation and migration theories can be tes…

HD 110067 c has an aligned orbit

J. Zak, H. M. J. Boffin, E. Sedaghati +25

Planetary systems in mean motion resonances hold a special place among the planetary population. They allow us to study planet formation in great detail as dissipative processes ar…

Stellar obliquity measurements of six gas giants

J. Zak, A. Bocchieri, E. Sedaghati +11

One can infer the orbital alignment of exoplanets with respect to the spin of their host stars using the Rossiter-McLaughlin effect, thereby giving us the chance to test planet for…

Periodic variable A-F spectral type stars in the northern TESS continuous viewing zone

M. Skarka, J. Žák, M. Fedurco +11

The goal of our study is to provide a reliable classification of variability of A-F stars brighter than 11 mag located in the northern TESS continuous viewing zone. We also aim at…
