An Impact Basin Thermometer for the Moon

by Laurent G. J. Montési 22 April 202216 June 2022

Large impact basins on the near side of the Moon lack the annulus of thickened crust that far-side basins have. The difference can be linked to the thermal structure of the lunar crust.

A Better Look at the Moon’s Middle Mantle

by Laurent G. J. Montési 8 November 20218 November 2021

A new analysis strategy sheds new light on the electrical conductivity of the lunar mantle between 300 and 900 km depth.

Shining a Spotlight on the Chicxulub Impact Crater

by Laurent G. J. Montési 12 October 20218 October 2021

A new seismic survey of the Chicxulub impact crater reveals the structure of its peak ring and the sediments that cover it.

How Not to Homogenize a Planet

by Laurent G. J. Montési 28 April 202112 October 2022

Even the strong heating from short-lived aluminium-26 (26Al) would not be able to homogenize the interior of a Mars‐sized planetary embryo.

The Tumbling Boulders of Orientale Basin

by Laurent G. J. Montési 8 February 20213 May 2022

Mapping boulder fields and boulder tracks highlights the seismic hazard still present on the Moon.

What Happened When the Lithosphere of Venus Broke?

by Laurent G. J. Montési 5 January 202115 March 2022

Although Venus does not have plate tectonics today, previous episodes of intense tectonic activity could have resulted in a distribution of crustal thickness and age resembling the plate we see today.

Predicting the Unique Shape of Craters on Asteroid (16) Psyche

by Laurent G. J. Montési 21 December 202015 February 2022

Models link the variety of crater shapes expected on (16) Psyche with the interior structure of this unique asteroid, in preparation for the arrival of the Psyche probe in 2026.

Traces of Impacts on Warm Planetesimals Early in Solar System

by Laurent G. J. Montési and J. Filiberto 9 October 20208 March 2022

Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.
