JWST unveils a high mean molecular weight atmosphere for mini-Neptune TOI-1130b: Evidence for formation beyond the water ice line
Saugata Barat, Tyler Fairnington, Shelby Courreges +21
We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R, 19.8 M, K). It is…
A high mutual inclination system around KOI-134 revealed by transit timing variations
Emma Nabbie, Chelsea X. Huang, Judith Korth +9
Few planetary systems have measured mutual inclinations, and even less are found to be non-coplanar. Observing the gravitational interactions between exoplanets is an effective too…
Evolution of Extremely Soft Binaries in Dense Star Clusters: On the Jupiter Mass Binary Objects
Yihan Wang, Rosalba Perna, Zhaohuan Zhu +1
Star-forming regions, characterized by dense environments, experience frequent encounters that significantly influence binary systems, leading to their hardening, softening, or ion…
Changing-Look AGN Behaviour Induced by Disk-Captured Tidal Disruption Events
Yihan Wang, Douglas N. C. Lin, Bing Zhang +1
Recent observations of changing-look active galactic nuclei (AGN) hint at a frequency of accretion activity not fully explained by tidal disruption events (TDEs) stemming from rela…
Dynamical Evolution of Closely Packed Multiple Planetary Systems Subject to Atmospheric Mass-Loss
S. Wang, D. N. C. Lin
A gap in exoplanets' radius distribution has been widely attributed to the photo-evaporation threshold of their progenitors' gaseous envelope. Giant impacts can also lead to substa…
An alternative model for the origin of gaps in circumstellar disks
Eduard I. Vorobyov, Zsolt Regaly, Manuel Guedel +1
Motivated by recent observational and numerical studies suggesting that collapsing protostellar cores may be replenished from the local environment, we explore the evolution of pro…
Are the Kepler Near-Resonance Planet Pairs due to Tidal Dissipation?
Man Hoi Lee, D. Fabrycky, D. N. C. Lin
The multiple-planet systems discovered by the Kepler mission show an excess of planet pairs with period ratios just wide of exact commensurability for first-order resonances like 2…
The Gemini NICI Planet-Finding Campaign: The Frequency of Giant Planets Around Debris Disk Stars
Zahed Wahhaj, Michael C. Liu, Eric L. Nielsen +17
We have completed a high-contrast direct imaging survey for giant planets around 57 debris disk stars as part of the Gemini NICI Planet-Finding Campaign. We achieved median H-band…
Internal Gravity Waves in Massive Stars: Angular Momentum Transport
T. M. Rogers, D. N. C. Lin, J. N. McElwaine +1
We present numerical simulations of internal gravity waves (IGW) in a star with a convective core and extended radiative envelope. We report on amplitudes, spectra, dissipation and…
The Gemini NICI Planet-Finding Campaign: The Frequency of Giant Planets around Young B and A Stars
Eric L. Nielsen, Michael C. Liu, Zahed Wahhaj +22
We have carried out high contrast imaging of 70 young, nearby B and A stars to search for brown dwarf and planetary companions as part of the Gemini NICI Planet-Finding Campaign. O…
Internal Gravity Waves Modulate the Apparent Misalignment of Exoplanets around Hot Stars
T. M. Rogers, D. N. C. Lin, H. H. B. Lau
We propose that the observed misalignment between extra-solar planets and their hot host stars can be explained by angular momentum transport within the host star. Observations hav…
The Importance of Disk Structure in Stalling Type I Migration
Katherine A. Kretke, D. N. C. Lin
As planets form they tidally interact with their natal disks. Though the tidal perturbation induced by Earth and super-Earth mass planets is generally too weak to significantly mod…
A Population of Very-Hot Super-Earths in Multiple-Planet Systems Should be Uncovered by Kepler
Kevin C. Schlaufman, D. N. C. Lin, S. Ida
We simulate a Kepler-like observation of a theoretical exoplanet population and we show that the observed orbital period distribution of the Kepler giant planet candidates is best…
Oxygen abundance of open cluster dwarfs
Z. -X. Shen, X. -W. Liu, H. -W. Zhang +2
We present oxygen abundances of dwarfs in the young open cluster IC 4665 deduced from the OI 7774 triplet lines and of dwarfs in the open cluster Pleiades derived from the [OI]…
Dust Distribution in Gas Disks. A Model for the Ring Around HR 4796A
Hubert Klahr, D. N. C. Lin
There have been several model analyses of the near and mid IR flux from the circumstellar ring around HR4796A. In the vicinity of a young star, the possibility that the dust ring i…
Evidence for an Intervening Stellar Population Toward the Large Magellanic Cloud
Dennis Zaritsky, D. N. C. Lin
We identify a vertical extension of the red clump stars in the color magnitude diagram (CMD) of a section of the Large Magellanic Cloud (LMC). After subtracting the principal red c…
