Gaps and Rings: A Near-Universal Trait of Extended Protoplanetary Discs
Quincy Bosschaart, Osmar M. Guerra-Alvarado, Nienke van der Marel +1
Substructures such as rings, gaps, and cavities are commonly observed in protoplanetary discs and are thought to play a key role in dust evolution and planet formation. However, a…
The Radius Cliff is a Waterfall: Explaining Sub-Neptune Exoplanets with Steam Worlds
Aritra Chakrabarty, Gijs D. Mulders, Artyom Aguichine +1
The demographics of Kepler planets provide a key testbed for models of planet formation and evolution, particularly for explaining the radius valley separating super-Earths and sub…
Are We There Yet? Challenges in Quantifying the Frequency of Earth Analogs in the Habitable Zone
Rachel B. Fernandes, Samson Johnson, Galen J. Bergsten +43
Searching for life elsewhere in the universe is one of the most highly prioritized pursuits in astronomy today. However, the ability to observe evidence of Earth-like life through…
Why Estimating is Difficult: A Kepler-Centric Perspective
Steve Bryson, Michelle Kunimoto, Ruslan Belikov +13
, the occurrence rate of rocky habitable zone exoplanets orbiting Sun-like stars, is of great interest to both the astronomical community and the general public. The Ke…
New migration patterns in high planet-star mass ratio systems in disks with low viscosity
Mariana Sánchez, Sijme-Jan Paardekooper, Nienke van der Marel +2
Migration of giant planets remains a complex topic. While significant progress has been made for high-viscosity disks, the migration of planets with large planet-star mass ratios i…
Diversity in planetary architectures from pebble accretion: Water delivery to the habitable zone with pebble snow
Sean McCloat, Gijs Mulders, Sherry Fieber-Beyer
"Pebble snow" describes a planet formation mechanism where icy pebbles in the outer disk reach inner planet embryos as the water ice line evolves inward. We model the effects pebbl…
ALMA High-resolution Observation for the Transitional Disk around IRAS 04125+2902
Ayumu Shoshi, Takayuki Muto, Quincy Bosschaart +5
Recently, the youngest transiting planet was discovered around the T Tauri star, IRAS 04125+2902, in the Taurus-Auriga star-forming region. This system is crucial for understanding…
Radius valley scaling among low mass stars with TESS
Harshitha M. Parashivamurthy, Gijs D. Mulders
The Transiting Exoplanet Survey Satellite (TESS) has been highly successful in detecting planets in close orbits around low-mass stars, particularly M dwarfs. This presents a valua…
A high-resolution survey of protoplanetary disks in Lupus and the nature of compact disks
Osmar M. Guerra-Alvarado, Nienke van der Marel, Jonathan P. Williams +4
Most of the exoplanets discovered in our galaxy to date orbit low-mass stars, which tend to host small disks in their early stages. To better elucidate the link between planet form…
Signatures of Atmospheric Mass Loss and Planet Migration in the Time Evolution of Short-Period Transiting Exoplanets
Rachel B. Fernandes, Galen J. Bergsten, Gijs D. Mulders +19
Comparative studies of young and old exoplanet populations offer a glimpse into how planets may form and evolve with time. We present an occurrence rate study of short-period (1…
Rocky planet formation in compact disks around M dwarfs
M. Sanchez, N. van der Marel, M. Lambrechts +2
Rocky planets in compact configurations are the most common ones around M dwarfs. Many disks around very low mass stars (between 0.1 and 0.5 M) are rather compact and small…
Small and Large Dust Cavities in Disks around mid-M Stars in Taurus
Yangfan Shi, Feng Long, Gregory J. Herczeg +10
High-angular resolution imaging by ALMA has revealed the near-universality and diversity of substructures in protoplanetary disks. However, disks around M-type pre-main-sequence st…
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…
Where are the Water Worlds? Identifying the Exo-water-worlds Using Models of Planet Formation and Atmospheric Evolution
Aritra Chakrabarty, Gijs D. Mulders
Planet formation models suggest that the small exoplanets that migrate from beyond the snowline of the protoplanetary disk likely contain water-ice-rich cores ( by mass)…
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,…
The Effect of Dust Evolution and Traps on Inner Disk Water Enrichment
Anusha Kalyaan, Paola Pinilla, Sebastiaan Krijt +6
Substructures in protoplanetary disks can act as dust traps that shape the radial distribution of pebbles. By blocking the passage of pebbles, the presence of gaps in disks may hav…
