Combined Effects of Disk Winds and Turbulence-Driven Accretion on Planet Populations
Matthew Alessi, Ralph E. Pudritz
Recent surveys show that protoplanetary disks have lower levels of turbulence than expected based on their observed accretion rates. A viable solution to this is that magnetized di…
Connecting planet formation and astrochemistry: C/O and N/O of warm giant planets and Jupiter-analogs
Alex J. Cridland, Ewine F. van Dishoeck, Matthew Alessi +1
(Abridged) The chemical composition of planetary atmospheres has long been thought to store information regarding where and when a planet accretes its material. Predicting this che…
Formation of Planetary Populations III: Core Composition & Atmospheric Evaporation
Matthew Alessi, Julie Inglis, Ralph E. Pudritz
The exoplanet mass radius diagram reveals that super Earths display a wide range of radii, and therefore mean densities, at a given mass. Using planet population synthesis models,…
Formation of Planetary Populations II: Effects of Initial Disk Size & Radial Dust Drift
Matthew Alessi, Ralph E. Pudritz, Alex J. Cridland
Recent ALMA observations indicate that while a range of disk sizes exist, typical disk radii are small, and that radial dust drift affects the distribution of solids in disks. Here…
Connecting planet formation and astrochemistry: A main sequence for C/O in hot-exoplanetary atmospheres
Alex J. Cridland, Ewine F. van Dishoeck, Matthew Alessi +1
To understand the role that planet formation history has on the observable atmospheric carbon-to-oxygen ratio (C/O) we have produced a population of astrochemically evolving protop…
Physics of Planet Trapping with Applications to HL Tau
Alex J. Cridland, Ralph E. Pudritz, Matthew Alessi
We explore planet formation in the HL Tau disk and possible origins of the prominent gaps and rings observed by ALMA. We investigate whether dust gaps are caused by dynamically tra…
Formation of Planetary Populations I: Metallicity & Envelope Opacity Effects
Matthew Alessi, Ralph E. Pudritz
We present a comprehensive body of simulations of the formation of exoplanetary populations that incorporate the role of planet traps in slowing planetary migration. The traps we i…
Connecting Planetary Composition with Formation
Ralph E. Pudritz, Alex J. Cridland, Matthew Alessi
The rapid advances in observations of the different populations of exoplanets, the characterization of their host stars and the links to the properties of their planetary systems,…
Composition of Early Planetary Atmospheres I: Connecting Disk Astrochemistry to the Formation of Planetary Atmospheres
Alex J. Cridland, Ralph E. Pudritz, Matthew Alessi
We present a model of the early chemical composition and elemental abundances of planetary atmospheres based on the cumulative gaseous chemical species that are accreted onto plane…
On the Formation and Chemical Composition of Super Earths
Matthew Alessi, Ralph E. Pudritz, Alex J. Cridland
Super Earths are the largest population of exoplanets and are seen to exhibit a rich diversity of compositions as inferred through their mean densities. Here we present a model tha…
A Catalog of Globular Cluster Systems: What Determines the Size of a Galaxy's Globular Cluster Population?
William E. Harris, Gretchen L. H. Harris, Matthew Alessi
We present a catalog of 422 galaxies with published measurements of their globular cluster (GC) populations. Of these, 248 are E galaxies, 93 are S0 galaxies, and 81 are spirals or…
Stokes shift in quantum wells: trapping versus thermalization
A. Polimeni, A. Patanè, M. Grassi Alessi +4
Low temperature photoluminescence and photoluminescence excitation measurements have been performed in a set of InGaAs/GaAs samples with different indium molar fraction, well width…
