Rocky sub-Neptunes formed by pebble accretion: Rain of rocks from polluted envelopes
Allona Vazan, Chris W. Ormel
Sub-Neptune planets formed in the protoplanetary disk accreted hydrogen-helium (H,He) envelopes. Planet formation models of sub-Neptunes formed by pebble accretion result in small…
Chemical footprints of giant planet formation. Role of planet accretion in shaping the C/O ratio of protoplanetary disks
Haochang Jiang, Yu Wang, Chris W. Ormel +2
Protoplanetary disks, the birthplaces of planets, commonly feature bright rings and dark gaps in both continuum and line emission maps. Accreting planets are interacting with the d…
Accretion of aerodynamically large pebbles
Helong Huang, Chris W. Ormel
Due to their aerodynamical coupling with gas, pebbles in protoplanetary discs can drift over large distances to support planet growth in the inner disc. In the past decade, this pe…
When, where, and how many planets end up in first-order resonances?
Shuo Huang, Chris Ormel
The theory of Type~I migration has been widely used in many studies. Transiting multi-planet systems offer us the opportunity to examine the consistency between observation and the…
Efficient planet formation by pebble accretion in ALMA rings
Haochang Jiang, Chris W. Ormel
In the past decade, ALMA observations have revealed that a large fraction of protoplanetary discs contains rings in the dust continuum. These rings are the locations where pebbles…
Hydrodynamics of Embedded Planets' First Atmospheres. II. A Rapid Recycling of Atmospheric Gas
Chris W. Ormel, Ji-Ming Shi, Rolf Kuiper
Following Paper I we investigate the properties of atmospheres that form around small protoplanets embedded in a protoplanetary disc by conducting hydrodynamical simulations. These…
