Bondi-Hoyle-Lyttleton Accretion onto a Protoplanetary Disk (2009)
Moeckel, Nickolas, Throop, Henry B.
Young stellar systems orbiting in the potential of their birth cluster can accrete from the dense molecular interstellar medium during the period between the star's birth and the dispersal of the...
Young stars orbiting in the gravitational potential well of forming star clusters pass through the cluster's dense molecular gas and can experience Bondi-Hoyle accretion from reservoirs outside their...
G Ring Particle Sizes Derived From Ring Plane Crossing Observations (2007)
Henry B. Throop, Larry W. Esposito, Henry Throop
The Saturn ring plane crossings in 1995--96 allowed observers using the Hubble Space Telescope and the W. M. Keck telescope to image the planet's diffuse rings from 0.3 ¯m -- 2.2 ¯m at a...
Evidence for Dust Grain Growth in Young Circumstellar Disks (2007)
Henry B. Throop, John Bally, Larry W. Esposito, Mark J. Mccaughrean
Hundreds of circumstellar disks in the Orion nebula are being rapidly destroyed by the intense ultraviolet radiation produced by nearby bright stars. These young million-year-old disks may not...
Can photo-evaporation trigger planetesimal formation? (2004)
We propose that UV radiation can stimulate the formation of planetesimals in externally-illuminated protoplanetary disks. We present a numerical model of disk evolution including vertical...
Phase light curves for extrasolar Jupiters and Saturns (2004)
Dyudina, Ulyana A., Sackett, Penny D., Bayliss, Daniel D. R., Seager, Sara, Porco, Carolyn C., Throop, Henry B., ...
We predict how a remote observer would see the brightness variations of giant planets similar to Jupiter and Saturn as they orbit their central stars. We model the geometry of Jupiter, Saturn and...
De La Fuente, Eduardo, Rosado, Margarita, Arias, Lorena, Ambrocio-Cruz, Patricia, Throop, Henry B.
In this paper, we present a briefly overview of the protoplanetary disks in the Orion Nebula, incluiding some astrobiological aspects and an H$\alpha$ Fabry-Perot study of 16 of them. We found that...
Evidence for dust grain growth in young circumstellar disks (2001)
Throop, Henry B., Bally, John, Esposito, Larry W., McCaughrean, Mark J.
Hundreds of circumstellar disks in the Orion nebula are being rapidly destroyed by the intense ultraviolet radiation produced by nearby bright stars. These young, million-year-old disks may not...
