Mid-infrared Imaging of SR 12 c with JWST/MIRI: Grain Growth in an Evolved Circumplanetary Disk

Ya-Lin Wu, Claire O. Finley, Brendan P. Bowler +13

The physical properties of circumplanetary disks offer insights into the formation of giant planets and their satellites. The circumbinary planetary-mass companion SR 12 c (1200 au…

Bridging the gap between stars and planets

Aina Palau, Dimitris Stamatellos, Matthew Bate +58

The formation mechanisms of brown dwarfs (BDs) and free-floating planets (FFPs) are poorly constrained. The two main competing scenarios include the star-like scenario, where these…

Chemistry on solar system scales

Catherine Walsh, Maria Drozdovskaya, Dmitry Semenov +33

The initial chemical composition of planets, primitive bodies in our solar system, and exoplanets is ultimately set by their nascent protoplanetary disks. Yet observing key carbon-…

Multi-wavelength Polarization as a Probe of Planet Formation

Ian Stephens, Sarah Sadavoy, Akimasa Kataoka +11

Polarization reveals details of circumstellar disks that are not readily available from total intensity observations. Via multi-wavelength polarimetric observations of disks, we ca…

Planet formation on solar system scales

Francesco Zagaria, Andrés F. Izquierdo, Jaehan Bae +32

Giant planets are often regarded as primordial protoplanetary "architects". Their formation and interactions with planetesimals and other planets during and after the protoplanetar…

Planet forming disk populations and their connection to the environment

Thomas J. Haworth, Giovanni Rosotti, Carlo Manara +35

Existing sub-mm observatories such as ALMA have provided statistics on the planet-forming mass reservoirs within circumstellar disks around stars in stellar clusters out to distanc…

GEMS JWST: Hold on to your HATS(-6 b), a sub-solar metallicity giant planet with water, methane and ammonia in its atmosphere

Giannina Guzmán Caloca, Caleb I. Cañas, Nicole L. Wallack +16

HATS-6 b is one of several recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) and is part of a JWST survey that aims to compare bulk and atmospheric properties of t…

Ultraviolet Imaging of SR 12 c with HST/WFC3: Accretion and Variability of a Giant Planet at the End Stages of Growth

Claire O. Finley, Brendan P. Bowler, Ya-Lin Wu +12

Many details of the gas accretion phase during giant planet formation remain untested. We present new 0.2$\unicode{x2013}$0.7 m UV-through-red optical imaging of the young, wide…

GEMS JWST: HATS-75 b -- A giant planet with a sub-solar metallicity atmosphere orbiting an M-dwarf

Reza Ashtari, Jacob Lustig-Yaeger, Jessica Libby-Roberts +12

HATS-75 b is one of the recently discovered Giant Exoplanets orbiting M-dwarf Stars (GEMS) with a transmission spectrum shaped by both its atmosphere and the active stellar surface…

GEMS JWST: A sub-Solar metallicity atmosphere for giant planet TOI-5293Ab orbiting a rapidly changing M-dwarf

Shubham Kanodia, Caleb I. Cañas, Jacob Lustig-Yaeger +13

The growing sample of Giant Exoplanets around M-dwarf Stars (GEMS) helps probe the extremes of giant planet formation. Comparing the properties of this sample with their FGK counte…

exoALMA XX: Tomographic Detection of Embedded Planets in Protoplanetary Disks

Andres F. Izquierdo, Jaehan Bae, Stefano Facchini +32

The exoALMA Large Program has revealed a wealth of substructures in the dust and molecular line emission of several protoplanetary discs, suggesting that planet formation may unfol…

exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks

Misato Fukagawa, Andrés F. Izquierdo, Jochen Stadler +35

Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes an…

exoALMA XXI: The Morphology and Dynamics of Vertical Flows

Myriam Benisty, Andres F. Izquierdo, Jochen Stadler +33

Vertical gas flows, such as winds and meridional circulations, are natural outcomes of protoplanetary disk processes and play a critical role in the earliest stages of planet forma…

exoALMA XIX: Confirmation of Non-thermal Line Broadening in the DM Tau Protoplanetary Disk

Caitlyn Hardiman, Christophe Pinte, Daniel J. Price +38

Turbulence is expected to transport angular momentum and drive mass accretion in protoplanetary disks. One way to directly measure turbulent motion in disks is through molecular li…
