TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system

Posted by dbos MIT

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Michaela Vítková, Rafael Brahm, Trifon Trifonov, Petr Kabáth, Andrés Jordán | Summary: We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit timing variations (TTVs), with a peak-to-node […]

The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Feng Long, Ilaria Pascucci, Adrien Houge, Andrea Banzatti, Klaus M. Pontoppidan | Summary: We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16$-$262756.1B (hereafter J0446B), an old ($sim$34 Myr) M4.5 star but with hints of ongoing accretion. The spectrum is molecule-rich and dominated […]

SZ-X-ray Surface Brightness Fluctuations in the SPT-XMM clusters

Posted by Chicago

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Charles Romero, Massimo Gaspari, Gerrit Schellenberger, Bradford A. Benson, Lindsey E. Bleem | Summary: The hot plasma in galaxy clusters, the intracluster medium (ICM), is expected to be shaped by subsonic turbulent motions, which are key for heating, cooling, and transport mechanisms. The turbulent motions contribute […]
