I wanted to leave a break for the holidays, but… this one’s a bit important. Astronomy and Astrophysics Review doesn’t print a lot, but the term “Review” means those papers it does print are substantial and significant. So: Bagnulo, S.… Read More »Pola-Review Paper
The Journal of Geophysical Research: Planets doesn’t often handle pristine relics from the dawn of the Solar System- ‘pristine’ implies a distinct lack of geophysics. Yet in Vol. 128, #12: Hartzell, C. M. Zhang, Y. Characterizing the Modulation and Activation-Triggering… Read More »Note, Paper: Not-So-Dark Comets

The EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects continues. For Tuesday, 11/12/24, we continued phase curves, but after that it was thermal infrared observations and polarimetry: https://indico.esa.int/event/530/contributions/ Absolute magnitudes and photometry from the MPC catalog Peter Vereš (Minor… Read More »Workshop: Size Determination of Potentially Hazardous NEOs pt.

And now for a little change of venue. With the obvious exception of “mini-moons” (TCOs and TCFs) asteroid targets are in heliocentric orbits, and often at ranges measured in AUs. Round-trip light time is a few minutes, and it’s unrealistic… Read More »Note, Paper: A-Robot
