Chemical Abundances Shape History (CASH). I. A Link between Giant Planets Orbital Periods and Host Stellar C/O Ratios
Ruisheng Zhang, Ji-Wei Xie, Mengrui Pan +5
The chemical abundance of host stars plays a pivotal role in shaping the formation history of planetary systems, yet the influence of elements beyond iron remains poorly understood…
A universal brown dwarf desert formed between planets and stars
Kaiming Cui, Guang-Yao Xiao, Fabo Feng +10
Giant planets and brown dwarfs play a crucial role in star and planet formation, as they are situated at the boundary between planets and stars with uncertain formation mechanisms.…
The impact of pre-main sequence stellar luminosity on giant planet formation
Heather F. Johnston, Olja Panić, Beibei Liu +1
Luminosities of pre-main sequence stars evolve during the protoplanetary disc lifetime. This has a significant impact on the heating of their surrounding protoplanetary disks, the…
Dependence of Planet populations on Stellar Mass and Metallicity: A Pebble Accretion-based Planet Population Synthesis
Mengrui Pan, Beibei Liu, Linjie Jiang +3
The formation and evolution of planetary systems are linked to their host stellar environment. In this study, we employ a pebble accretion-based planet population synthesis model t…
Forming Giant Planets Around Late-M Dwarfs: Pebble Accretion and Planet-Planet Collision
Mengrui Pan, Beibei Liu, Anders Johansen +6
We propose a pebble-driven core accretion scenario to explain the formation of giant planets around the late-M dwarfs of . In order to explore th…
Formation of giant planets around intermediate-mass stars
Heather Johnston, Olja Panic, Beibei Liu
To understand giant planet formation, we need to focus on host stars close to , where the occurrence rate of these planets is the highest. In this initial study…
