Lecture 1 - Introduction
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
Professor Bailyn introduces the course and discusses the course material and requirements. The three major topics that the course will cover are (1) exoplanets--planets around stars other than the Sun, (2) black holes--stars whose gravitational pull is so strong that even their own light rays cannot ...

Lecture 2 - Planetary Orbits
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
Exoplanets are introduced and students learn how astronomers detect their presence as well as the challenges associated with it. Physics equations are explained as well as their importance in the context of the course. A number of problems are worked out to get students used to dealing with large nu ...

Lecture 3 - Our Solar System and the Pluto Problem
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
Class begins with a review of the first problem set. Newton's Third Law is applied in explaining how exoplanets are found. An overview of the Solar System is given; each planet is presented individually and its special features are highlighted. Astronomy is discussed as an observational science, and ...

Lecture 4 - Discovering Exoplanets: Hot Jupiters
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
The formation of planets is discussed with a special emphasis on the bodies in the Solar System. Planetary differences between the celestial bodies in the Inner and Outer Solar System are observed. Professor Bailyn explains how the outlook of our Solar System can predict what other star systems may ...

Lecture 5 - Planetary Transits
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
Professor Bailyn talks about student responses for a paper assignment on the controversy over Pluto. The central question is whether the popular debate is indeed a "scientific controversy." A number of scientific "fables" are discussed and a moral is associated with each: the demotion of Pluto (mora ...

Lecture 6 - Microlensing, Astrometry and Other Methods
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
The class begins with a discussion on transits – important astronomical events that help astronomers to find new planets. The event occurs when a celestial body moves across the face of the star it revolves around and blocks some of its light. By calculating the amount of light that is being obscure ...

Lecture 7 - Direct Imaging of Exoplanets
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
Class begins with a problem on transits and learning what information astronomers obtain through observing them. For example, radii of stars can be estimated. Furthermore, applying the Doppler shift method, one can find the mass of a star. Finally, a star's density can be calculated. A second method ...

Lecture 8 - Introduction to Black Holes
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
The second half of the course begins, focusing on black holes and relativity. In introducing black holes, Professor Bailyn offers a definition, talks about how their existence is detected, and explains why (unlike in the case with exoplanets where Newtonian physics was applied) Einstein's Theory of ...

Lecture 9 - Special and General Relativity
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
The discussion of black holes continues with an introduction of the concept of event horizon. A number of problems are worked out to familiarize students with mathematics related to black hole event horizons. In a longer question and answer session, Professor Bailyn discusses the more mystifying asp ...

Lecture 10 - Tests of Relativity
Charles Bailyn , Yale University
Video in druga učna gradiva
Oznake: astronomy
The lecture begins with the development of post-Newtonian approximations from Newtonian terms. Several problems are worked out in calculating mass, force and energy. A discussion follows about how concepts like mass and velocity are approached differently in Newtonian physics and Relativity. Attenti ...
