Cratering Chronology and the Evolution of Mars
- W. Hartmann, G. Neukum
- Geology
- 1 April 2001
Results by Neukum et al. (2001) and Ivanov (2001) are combined with crater counts to estimate ages of Martian surfaces. These results are combined with studies of Martian meteorites (Nyquist et al.,… Expand
Martian cratering 8: Isochron refinement and the chronology of Mars
- W. Hartmann
- Geology
- 1 April 2005
Abstract This paper reviews and refines the technique of dating martian surfaces by using impact-crater isochrons (defined as size distributions of impact craters on undisturbed martian surfaces of… Expand
Meteorite Delivery via Yarkovsky Orbital Drift
- P. Farinella, D. Vokrouhlicky, W. Hartmann
- Physics
- 1 April 1998
Abstract We provide a unified discussion of the Yarkovsky effect in both the original, “diurnal” variant and also for the “seasonal” variant which has been recently shown by Rubincam (1995) to be… Expand
Cratering Records in the Inner Solar System in Relation to the Lunar Reference System
- G. Neukum, B. Ivanov, W. Hartmann
- Geology
- 1 April 2001
The well investigated size-frequency distributions (SFD) for lunar craters is used to estimate the SFD for projectiles which formed craters on terrestrial planets and on asteroids. The result shows… Expand
The Time-Dependent Intense Bombardment of the Primordial Earth/Moon System
- W. Hartmann, G. Ryder, L. Dones, D. Grinspoon
- Geology, Physics
- 2000
This invention relates to a unique, improved, inexpensive, one-piece garment or equipment hanger which can be securely attached to the diagonal rod or wire, of which the common chain link type fence… Expand

Satellite-Sized Planetesimals and Lunar Origin
- W. Hartmann, D. R. Davis
- Geology
- 1 April 1975
Abstract Exploratory calculations using accretionary theory are made to demonstrate plausible sizes of second-largest, third-largest, etc., bodies at the close of planet formation in heliocentric… Expand
Recent Fluvial, Volcanic, and Tectonic Activity on the Cerberus Plains of Mars
- D. C. Berman, W. Hartmann
- Geology
- 1 September 2002
Athabasca and Marte Valles lie on the Cerberus plains, between the young, lava-covered plains of Elysium Planitia and Amazonis Planitia. To test pre-MGS (Mars Global Surveyor) suggestions of… Expand
Asteroids - The big picture
- J. Bell, D. R. Davis, W. Hartmann, M. Gaffey
- Geology
- 1989
An attempt is made to construct a simple model of the evolution of the asteroid belt from the data available about the individual asteroids. Data on the meaning of taxonomic types, the stratigraphy… Expand

Planetesimals to planets: Numerical simulation of collisional evolution
- R. Greenberg, J. F. Wacker, J. F. Wacker, W. Hartmann, CARLETONB. Chapman
- Physics
- 1 July 1978
A simulation of collisional and gravitational interaction in the early solar system generates planets ∼500 km in diameter from an initial swarm of kilometer-sized planetesimals, such as might have… Expand
