The Boundary between Gas-rich and Gas-poor Planets by Lee, Eve J.

“…Sub-Saturns straddle the boundary between gas-rich Jupiters and gas-poor super-Earths/sub-Neptunes. Their large radii (4-8 R⊕) suggest that their gas-to-core…”

BREEDING SUPER-EARTHS AND BIRTHING SUPER-PUFFS IN TRANSITIONAL DISKS by Lee, Eve J., Chiang, Eugene

“…ABSTRACT The riddle posed by super-Earths (1-4R⊕, 2-20M⊕) is that they are not Jupiters: their core masses are large enough to trigger runaway gas accretion,…”

TO COOL IS TO ACCRETE: ANALYTIC SCALINGS FOR NEBULAR ACCRETION OF PLANETARY ATMOSPHERES by Lee, Eve J., Chiang, Eugene

“…ABSTRACT Planets acquire atmospheres from their parent circumstellar disks. We derive a general analytic expression for how the atmospheric mass grows with…”

Magnetospheric Truncation, Tidal Inspiral, and the Creation of Short-period and Ultra-short-period Planets by Lee, Eve J., Chiang, Eugene

“…Sub-Neptunes around FGKM dwarfs are evenly distributed in log orbital period down to ∼10 days, but dwindle in number at shorter periods. Both the break at ∼10…”

A PRIMER ON UNIFYING DEBRIS DISK MORPHOLOGIES by Lee, Eve J., Chiang, Eugene

“…ABSTRACT A "minimum model" for debris disks consists of a narrow ring of parent bodies, secularly forced by a single planet on a possibly eccentric orbit,…”

MAKE SUPER-EARTHS, NOT JUPITERS: ACCRETING NEBULAR GAS ONTO SOLID CORES AT 0.1 AU AND BEYOND by Lee, Eve J, Chiang, Eugene, Ormel, Chris W

“…Close-in super-Earths having radii 1-4 R may possess hydrogen atmospheres comprising a few percent by mass of their rocky cores. We determine the conditions…”

Creating the Radius Gap without Mass Loss by Lee, Eve J., Karalis, Amalia, Thorngren, Daniel P.

“…The observed exoplanet population features a gap in the radius distribution that separates the smaller super-Earths (≲1.7 Earth radii) from the larger…”

Probing Dust and Gas Properties Using Ringed Disks by Lee, Eve J.

“…How rapidly a planet grows in mass and how far it may park from the host star depend sensitively on two nondimensional parameters: Stokes number St and…”

PHYSICAL PROPERTIES OF MOLECULAR CLOUDS FOR THE ENTIRE MILKY WAY DISK by Miville-Deschênes, Marc-Antoine, Murray, Norman, Lee, Eve J.

“…ABSTRACT This study presents a catalog of 8107 molecular clouds that covers the entire Galactic plane and includes 98% of the 12CO emission observed within …”

Primordial Radius Gap and Potentially Broad Core Mass Distributions of Super-Earths and Sub-Neptunes by Lee, Eve J., Connors, Nicholas J.

“…The observed radii distribution of Kepler exoplanets reveals two distinct populations: those that are more likely to be terrestrials ( 1.7R⊕) and those that…”

Sculpting the Sub-Saturn Occurrence Rate via Atmospheric Mass Loss by Hallatt, Tim, Lee, Eve J.

“…The sub-Saturn (∼4–8 R ⊕ ) occurrence rate rises with orbital period out to at least ∼300 days. In this work we adopt and test the hypothesis that the decrease…”

Inner Super-Earths, Outer Gas Giants: How Pebble Isolation and Migration Feedback Keep Jupiters Cold by Fung, Jeffrey, Lee, Eve J.

“…The majority of gas giants (planets of masses 102 M⊕) are found to reside at distances beyond ∼1 au from their host stars. Within 1 au, the planetary…”

The Not-so Dramatic Effect of Advective Flows on Gas Accretion by Savignac, Vincent, Lee, Eve J.

“…Super-Earths and mini-Neptunes are the most common types of exoplanets discovered, yet the physics of their formation are still debated. Standard core…”

TIME-VARYING DYNAMICAL STAR FORMATION RATE by Lee, Eve J, Chang, Philip, Murray, Norman

“…We present numerical evidence of dynamic star formation in which the accreted stellar mass grows superlinearly with time, roughly as t super(2). We perform…”

OBSERVATIONAL EVIDENCE OF DYNAMIC STAR FORMATION RATE IN MILKY WAY GIANT MOLECULAR CLOUDS by Lee, Eve J., Miville-Deschênes, Marc-Antoine, Murray, Norman W.

“…ABSTRACT Star formation on galactic scales is known to be a slow process, but whether it is slow on smaller scales is uncertain. We cross-correlate 5469 giant…”
