TLDR
In this article, the authors made an attempt to not only review but reopen the debate on non-linear meteor trails, and found that approximately one in every two hundred of the visual meteors is likely to show a nonlinear trail, and that of such trails about 60% will be continuously curved and 40% sinusoidal.Abstract:
In this essay an attempt is made to not only review but reopen the debate on non-linear meteor trails. On the basis of data culled from various, now historical, sources it is found that approximately one in every two hundred of the visual meteors is likely to show a non-linear trail, and that of such trails about 60% will be continuously curved and 40% sinusoidal. It is suggested that two mechanisms may explain the various trail types: the continuously curved trails being a manifestation of the classical Magnus effect, and the sinusoidal trails resulting from torque-free precession.read more

Are meteoroids really dustballs
TL;DR: In this article, the authors present theoretical results for wake production as a function of grain mass distribution, grain height of separation, zenith angle and velocity, and show that most meteoroids are collections of hundreds to thousands of fundamental grains at least some of which are released prior to the onset of intensive ablation.

Curveballs in protoplanetary discs – the effect of the Magnus force on planet formation
TL;DR: In this paper, the authors examined the effect of the Magnus force on the dynamics of a gaseous protoplanetary disk and found that it can prevent the formation of planetesimals via gravitational instability in the inner disk if the size of the dust particles is larger than 10 cm.

Rotation of cometary meteoroids
TL;DR: In this paper, the rotational characteristics of ejected meteoroid population were obtained by numerical integration of equations of motion with random initial conditions and random shape selection, which can serve as initial conditions for further analyses of subsequent evolution of rotation in the interplanetary space.

Rotation of cometary meteoroids
TL;DR: In this article, the rotational characteristics of meteoroids after their release from a comet during normal activity were determined analytically, and the basic dependence of spin rate on ejection velocity and meteoroid size was determined.

Classical Mechanics: A Modern Perspective
TL;DR: In this paper, the Lagrangian method was used to solve the Lorentz transformation problem in a simple pendulum coupled harmonic oscillator with damping resonance, and the solution was shown to be a solution to the equation of motion of a single-axis rotation of a billiard ball.

Effect of Spin and Speed on the Lateral Deflection (Curve) of a Baseball; and the Magnus Effect for Smooth Spheres
TL;DR: In this article, the effect of spin and speed on the lateral deflection of a baseball has been measured by dropping the ball while spinning about a vertical axis through the horizontal wind stream of a 6-ft tunnel.

Rotational bursting of small celestial bodies: Effects of radiation pressure
TL;DR: In this paper, it was estimated that actual nonmagnetic meteorites and tektites will reach bursting speed in about 60,000 years, and a time to bursting of about sixty years was calculated for an idealized body.
