Oxygen isotopic compositions of fresh rooftop micrometeorites from the Budel collection—Insights into the contemporary cosmic dust flux

open access: yesMeteoritics &Planetary Science, Volume 59, Issue 6, Page 1236-1257, June 2024.
Abstract Cosmic dust particles originate from a wide variety of solar system and interstellar objects, including sources not identified among meteorite collections. Particles that survive atmospheric entry are retrieved on the Earth's surface as micrometeorites. The recovery of these micrometeorites has recently advanced to rooftop sites.

The Composition of Dust in Jupiter-Family Comets as Inferred from Infrared Spectroscopy [PDF]

open access: yes, 2008
We review the composition of Jupiter-family comet dust as inferred from infrared spectroscopy. We find that Jupiter-family comets have 10 micron silicate emission features with fluxes roughly 20-25% over the dust continuum (emission strength 1.20-1.25), similar to the weakest silicate features in Oort Cloud comets.

The Carbon Monoxide Abundance in Comet 103P/Hartley during the EPOXI Flyby

open access: yes, 2011
We report the detection of several emission bands in the CO Fourth Positive Group from comet 103P/Hartley during ultraviolet spectroscopic observations from the Hubble Space Telescope (HST) on 2010 November 4 near the time of closest approach by NASA's ...

Shape of Big Rockets [PDF]

open access: yesarXiv, 2020
Recent publications discuss the size of chemical rockets for long-distance travel, to be launched from a planet. Here I point out that such a rocket cannot be tall and slim but will be short and fat.

The Relationship between Centaurs and Jupiter Family Comets with Implications for K-Pg-type Impacts [PDF]

open access: yes, 2019
Centaurs--icy bodies orbiting beyond Jupiter and interior to Neptune--are believed to be dynamically related to Jupiter Family Comets (JFCs), which have aphelia near Jupiter's orbit and perihelia in the inner Solar System. Previous dynamical simulations have recreated the Centaur/JFC conversion, but the mechanism behind that process remains poorly ...
