An Updated SynthPop Model for Microlensing Simulations I: Model Description & Evaluation
Macy J. Huston, Alison L. Crisp, Marz Newman +21
The optimization and interpretation of microlensing surveys depends on having an accurate model of the Milky Way. However, existing population synthesis Galactic modeling tools oft…
Scaling K2 VII: Evidence for a high occurrence rate of hot sub-Neptunes at intermediate ages
Jessie L. Christiansen, Jon K. Zink, Kevin K. Hardegree-Ullman +6
The NASA K2 mission obtained high precision time-series photometry for four young clusters, including the near-twin 600-800 Myr-old Praesepe and Hyades clusters. Hot sub-Neptunes a…
No Evidence for More Earth-sized Planets in the Habitable Zone of Kepler's M versus FGK Stars
Galen J. Bergsten, Ilaria Pascucci, Kevin K. Hardegree-Ullman +3
Reliable detections of Earth-sized planets in the habitable zone remain elusive in the Kepler sample, even for M dwarfs. The Kepler sample was once thought to contain a considerabl…
Using Photometrically-Derived Properties of Young Stars to Refine TESS's Transiting Young Planet Survey Completeness
Rachel B. Fernandes, Kevin K. Hardegree-Ullman, Ilaria Pascucci +7
The demographics of young exoplanets can shed light onto their formation and evolution processes. Exoplanet properties are derived from the properties of their host stars. As such,…
Two Warm Neptunes transiting HIP 9618 revealed by TESS & Cheops
Hugh P. Osborn, Grzegorz Nowak, Guillaume Hébrard +126
HIP 9618 (HD 12572, TOI-1471, TIC 306263608) is a bright ( mag) solar analogue. TESS photometry revealed the star to have two candidate planets with radii of …
Scaling K2. VI. Reduced Small Planet Occurrence in High Galactic Amplitude Stars
Jon K. Zink, Kevin K. Hardegree-Ullman, Jessie L. Christiansen +13
In this study, we performed a homogeneous analysis of the planets around FGK dwarf stars observed by the Kepler and K2 missions, providing spectroscopic parameters for 310 K2 targe…
Enabling Exoplanet Demographics Studies with Standardized Exoplanet Survey Meta-Data
Prepared by the ExoPAG Science Interest Group, 2 on Exoplanet Demographics, Jessie L. Christiansen +18
Goal 1 of the National Academies of Science, Engineering and Mathematics Exoplanet Science Strategy is "to understand the formation and evolution of planetary systems as products o…
The Demographics of Kepler's Earths and super-Earths into the Habitable Zone
Galen J. Bergsten, Ilaria Pascucci, Gijs D. Mulders +2
Understanding the occurrence of Earth-sized planets in the habitable zone of Sun-like stars is essential to the search for Earth analogues. Yet a lack of reliable Kepler detections…
Pterodactyls: A Tool to Uniformly Search and Vet for Young Transiting Planets In TESS Primary Mission Photometry
Rachel B. Fernandes, Gijs D. Mulders, Ilaria Pascucci +8
Kepler's short-period exoplanet population has revealed evolutionary features such as the Radius Valley and the Hot Neptune desert that are likely sculpted by atmospheric loss over…
Mass loss by atmospheric escape from extremely close-in planets
Tommi Koskinen, Panayotis Lavvas, Chenliang Huang +3
We explore atmospheric escape from close-in exoplanets with the highest mass loss rates. First, we locate the transition from stellar X-ray and UV-driven escape to rapid Roche lobe…
The Mass Budgets and Spatial Scales of Exoplanet Systems and Protoplanetary Disks
Gijs D. Mulders, Ilaria Pascucci, Fred J. Ciesla +1
Planets are born from disks of gas and dust, and observations of protoplanetary disks are used to constrain the initial conditions of planet formation. However, dust mass measureme…
Variability of Disk Emission in Pre-Main Sequence and related Stars. V. Occultation Events from the innermost disk region of the Herbig Ae Star HD 163296
Monika Pikhartova, Zachary C. Long, Korash D. Assani +8
HD 163296 is a Herbig Ae star that underwent a dramatic 0.8 magnitude drop in brightness in the V photometric band in 2001 and a brightening in the near-IR in 2002. Because t…
No Sub-Saturn Mass Planet Desert in the CORALIE/HARPS Radial Velocity Sample
David P. Bennett, Clément Ranc, Rachel B. Fernandes
We analyze the CORALIE/HARPS sample of exoplanets (Mayor et al. 2011) found by the Doppler radial velocity method for signs of the predicted "desert" at 10- caused by…
Hints for a Turnover at the Snow Line in the Giant Planet Occurrence Rate
Rachel B. Fernandes, Gijs D. Mulders, Ilaria Pascucci +2
The orbital distribution of giant planets is crucial for understanding how terrestrial planets form and predicting yields of exoplanet surveys. Here, we derive giant planets occurr…
Differences in the gas and dust distribution in the transitional disk of a sun-like young star, PDS 70
Zachary C. Long, Eiji Akiyama, Michael Sitko +22
We present ALMA 0.87 mm continuum, HCO+ J=4--3 emission line, and CO J=3--2 emission line data of the disk of material around the young, Sun-like star PDS 70. These data reveal the…
A Universal Break in the Planet-to-Star Mass-Ratio Function of Kepler MKG stars
Ilaria Pascucci, Gijs D. Mulders, Andrew Gould +1
We follow the microlensing approach and quantify the occurrence of Kepler exoplanets as a function of planet-to-star mass ratio, q, rather than planet radius or mass. For planets w…
Variability of Disk Emission in Pre-Main Sequence and Related Stars IV. Investigating the Structural Changes in the Inner Disk Region of MWC 480
Rachel B. Fernandes, Zachary C. Long, Monika Pikhartova +8
We present five epochs of near IR observations of the protoplanetary disk around MWC 480 (HD31648) obtained with the SpeX spectrograph on NASA's Infrared Telescope Facility (IRTF)…
