    Magnetized Protoplanetary Disks around Young Stars in the Presence of Realistic Cooling by Hanifeh Ghanbarnejad, Maryam Ghasemnezhad

    Published 2025-01-01
    “…Additionally, we calculated the cooling timescale in our model to assess one possible fragmentation condition necessary for planet formation. Our results indicate that, although the gravitational instability condition exists in the midplane of the disk, the cooling timescale is not short enough ( τ _cool  ≈ 1000Ω ^−1 ), and one possible mechanism for planet formation is not met.…”

    Characterization and modelling of exoplanetary atmospheres by Charnay, Benjamin, Drossart, Pierre

    Published 2023-04-01
    “…The arrival of JWST data and the development of new instruments on Earth will drastically modify the situation, giving access to deeper modelling contraints and to a better understanding on planet formation and evolution. This paper is devoted to describe the turning point experienced by the astronomy of exoplanets that will continue in particular with the launch of the ESA/Ariel mission at the end of the decade.…”

    Effects of Thermodynamics on the Concurrent Accretion and Migration of Gas Giants in Protoplanetary Disks by Hening Wu, Ya-Ping Li

    Published 2024-12-01
    “…Accretion and migration usually proceed concurrently for giant planet formation in the natal protoplanetary disks. Recent works indicate that the concurrent accretion onto a giant planet imposes significant impact on the planetary migration dynamics in the isothermal regime. …”

    Laboratory Measurement of CH317OH Transitions in the Frequency Range from 216 to 264 GHz for Astronomical Application by Akemi Tamanai, Takahiro Oyama, Yoshimasa Watanabe, Takeshi Sakai, Riouhei Nakatani, Shaoshan Zeng, Isabelle Kleiner, Nami Sakai

    Published 2025-01-01
    “…The newly obtained ^12 CH _3 ^17 OH data will play an important role in facilitating a deeper understanding of the organic chemistry related to star and planet formation. The ^12 CH _3 ^17 OH line data allow us to trace and constrain the isotopic ratio ^17 O/ ^18 O in methanol, which is efficient to investigate the galactic-scale evolution of elements. …”

    Sequencing Silicates in the Spitzer Infrared Spectrograph Debris Disk Catalog. I. Methodology for Unsupervised Clustering by Cicero X. Lu, Tushar Mittal, Christine H. Chen, Alexis Y. Li, Kadin Worthen, B. A. Sargent, Carey M. Lisse, G. C. Sloan, Dean C. Hines, Dan M. Watson, Isabel Rebollido, Bin B. Ren, Joel D. Green

    Published 2025-01-01
    “…Debris disks, which consist of dust, planetesimals, planets, and gas, offer a unique window into the mineralogical composition of their parent bodies, especially during the critical phase of terrestrial planet formation spanning 10 yr to a few hundred million years. …”
