Context. Mars-crossing asteroids (MCs) are a dynamically unstable group between the main belt and the near-Earth populations. Characterising the physical properties of a large sample of MCs can help to understand the original sources of many near-Earth asteroids, some of which may produce meteorites on Earth. Aims. Our aim is to provide diameters and albedos of MCs with available WISE/NEOWISE data. Methods. We used the near-Earth asteroid thermal model to find the best-fitting values of… Expand

Super-catastrophic disruption of asteroids at small perihelion distances
TLDR
It is found that low-albedo asteroids are more likely to be destroyed farther from the Sun, which explains the apparent excess of high- albedo near-Earth objects and suggests thatLow-al Bedrock asteroids break up more easily as a result of thermal effects. Expand
