Weather Radar Detection and Analysis of Bolides in the Day or Night

Advances in Astronomy
Weather radars have proven to be valuable tools for detection and analysis of meteorite falls, specifically identifying and analyzing falling meteorites which have survived the initial fireball.

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

Heat Transfer, Volume 55, Issue 1, Page 44-55, January 2026.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

The Utility of Infrasound in Global Monitoring of Extraterrestrial Impacts: A Case Study of the 2008 July 23 Tajikistan Bolide

The Astronomical Journal
Among the various observational techniques used for the detection of large bolides on a global scale is a low-frequency sound known as infrasound. Infrasound, which is also one of the four sensing modalities used by the International Monitoring System ...

Multiparameter Constraints on Empirical Infrasound Period-Yield Relations for Bolides and Implications for Planetary Defense

The Astronomical Journal
How effective are methods for estimating bolide energies from infrasound signal period-yield relationships? A single global period–energy relation can obscure significant variability introduced by parameters such as the atmospheric Doppler wind profile ...

Apache Point Rapid Response Characterization of Primitive Imminent Impactor 2024 RW1

The Astronomical Journal
Imminent impactors may be detected only a few hours before their impact with Earth, providing a brief opportunity to characterize them before impact. We describe the characterization of imminent impactor 2024 RW _1 , which was discovered by the Catalina ...

Atmospheric effects on crater growth on Venus [PDF]

Laboratory experiments allow examining the consequences of complex processes operating over a wide range of scales (both temporal and spatial) and frequently reveal effects that are obvious only in hindsight.

Astronomy with Small Telescopes

, 2006
The All Sky Automated Survey (ASAS) is monitoring all sky to about 14 mag with a cadence of about 1 day; it has discovered about 10^5 variable stars, most of them new. The instrument used for the survey had aperture of 7 cm.

Carbon source from limestone target by impact reaction at the K/T Boundary [PDF]

, 1999
Carbon found at the K/T geological boundaries can be explained by impact reaction between the K/T bolides and limestone target rocks, which are proved by other natural and artificial ...
