Key work on conducting a qualitative study using content analysis

A key work for understanding different types of content analysis.

This study provides comprehensive data on Yarkovsky-driven changes in eccentricity and longitude of periapse. By exploring a broad range of physical and orbital parameters, the results complement the drift rates in semi-major axis previously established by Spitale and Greenberg (2001).

It is shown that the average thermal inertia of a sample of NEAs in the km-size range is 200 ± 40 J m^−2 s^−0.5 K^−1 and it is identified a trend of increasing thermal inertia with decreasing asteroid diameter.

Arecibo radar ranging of NEA 6489 Golevka (diameter ~ 0.5 km) confirms the presence of Yarkovsky-driven orbital drift. This non-gravitational perturbation was isolated by comparing the asteroid's observed trajectory against purely Newtonian dynamical models.

By developing and numerically verifying an analytical model that includes Yarkovsky–Schach and planetary thermal effects, the researchers demonstrated that the Yarkovsky force significantly impacts mutual binary orbits. This orbital evolution occurs specifically in non-synchronous systems, where the spin and orbital periods differ, opening up new possibilities for understanding how binary systems migrate over time.

By measuring non-gravitational orbital drift, this study identifies the Yarkovsky effect across the NEA population. The reliability of these detections is maintained through a high-precision model—incorporating relativistic terms and the mass of 16 large asteroids—combined with specialized astrometric error treatment.

They used the determined rotation state, shape, size and thermophysical model of Apophis to predict the strength of the Yarkovsky effect in its orbit.

In this paper was investigated the possibility of detecting the Yarkovsky effect via precise orbit determination of near-Earth asteroids.

The study summarizes the knowledge about Yarkovsky, YORP, BYORP effects up to 2015.

A key comprehensive book on self-determination theory. If you don’t want to read all the articles and want a single source, you won’t find a better option.

A chapter in a Personality Psychology book devoted to self-determination theory. An alternative to the “full” version from the 2017 book if you want to save time.

Experimental confirmation that a reward can trigger a shift in motivation from intrinsic to extrinsic.

An excellent overview article on self-determination theory. A bit shorter than the book. Useful for a “quick” understanding of the theory.

An empirical measure within the framework of Self-Determination Theory that identifies causal orientation (autonomous, external, or impersonal). The primary instrument for the corresponding construct.

The purpose of this paper is to draw attention to failures in computation of asteroid synthetic proper elements with a goal to point out the dynamical or computational causes of the failures.

They computed Lyapunov times for a sample of trans-Neptunian objects and outer main-belt asteroids using three numerical approaches: the variational method and two implementations of the renormalization technique.
