Magnetically Driven Obliquity in Circumplanetary Disks and Twisted Bipolar-jet Formation
Raúl O. Chametla, Martin E. Pessah, F. Javier Sánchez-Salcedo +4
Circumplanetary disks (CPDs) regulate gas accretion onto forming giant planets and provide the environment in which their satellites may form. We use high-resolution, global three-…
Dynamics of planetary rings under thermal forces
Wen-Han Zhou, Eiichiro Kokubo, Harrison Agrusa +5
Planetary rings provide natural laboratories for studying the fundamental processes that govern the evolution of planetary systems. However, several key features, such as the sharp…
The Dynamical Origins of the Dark Comets and a Proposed Evolutionary Track
Aster G. Taylor, Jordan K. Steckloff, Darryl Z. Seligman +5
So-called 'dark comets' are small, morphologically inactive near-Earth objects (NEOs) that exhibit nongravitational accelerations inconsistent with radiative effects. These objects…
The Yarkovsky effect on the long-term evolution of binary asteroids
Wen-Han Zhou, David Vokrouhlicky, Masanori Kanamaru +4
We explore the Yarkovsky effect on small binary asteroids. While significant attention has been given to the binary YORP effect, the Yarkovsky effect is often overlooked. We develo…
NEOMOD 3: The Debiased Size Distribution of Near Earth Objects
David Nesvorny, David Vokrouhlicky, Frank Shelly +9
Our previous model (NEOMOD2) for the orbital and absolute magnitude distribution of Near Earth Objects (NEOs) was calibrated on the Catalina Sky Survey observations between 2013 an…
NEOMOD 2: An Updated Model of Near-Earth Objects from a Decade of Catalina Sky Survey Observations
David Nesvorny, David Vokrouhlicky, Frank Shelly +9
Catalina Sky Survey (CSS) is a major survey of Near-Earth Objects (NEOs). In a recent work, we used CSS observations from 2005-2012 to develop a new population model of NEOs (NEOMO…
Seasonally Varying Outgassing as an Explanation for Dark Comet Accelerations
Aster G. Taylor, Davide Farnocchia, David Vokrouhlicky +3
Significant nonradial, nongravitational accelerations with magnitudes incompatible with radiation-driven effects have been reported in seven small, photometrically inactive near-Ea…
(208) Lacrimosa: A case that missed the Slivan state?
D. Vokrouhlický, J. Ďurech, J. Hanuš +3
The largest asteroids in the Koronis family (sizes km) have very peculiar rotation state properties, with the retrograde- and prograde-rotating objects being distinctly d…
The Yarkovsky and YORP Effects
D. Vokrouhlicky, W. F. Bottke, S. R. Chesley +2
The Yarkovsky effect describes a small but significant force that affects the orbital motion of meteoroids and asteroids smaller than kilometers in diameter. It is caused b…
Near Earth Asteroids with measurable Yarkovsky effect
D. Farnocchia, S. R. Chesley, D. Vokrouhlicky +2
We seek evidence of the Yarkovsky effect among Near Earth Asteroids (NEAs) by measuring the Yarkovsky-related orbital drift from the orbital fit. To prevent the occurrence of unrel…
Detection of Semi-Major Axis Drifts in 54 Near-Earth Asteroids: New Measurements of the Yarkovsky Effect
C. R. Nugent, J. L. Margot, S. R. Chesley +1
We have identified and quantified semi-major axis drifts in Near-Earth Asteroids (NEAs) by performing orbital fits to optical and radar astrometry of all numbered NEAs. We focus on…
