Astrofisika


"Kita harus meningkatkan kuantitas dan kualitas kebaikan. Kuantitas bisa dilihat dari frekuensi dan besarnya apa yang Kita berikan kepada orang lain. Sementara kualitas manfaat ditingkatkan dengan cara meningkatkan kualitas diri, yaitu dengan meningkatkan keterampilan dan kemampuan, sehingga apa yang Kita berikan semakin bermanfaat."

Lecture 14 - Pulsars 

 

 

 

Overview:

 

Professor Bailyn begins with a summary of the four post-Newtonian effects of general relativity that were introduced and explained last time: precession of the perihelion, the deflection of light, the gravitational redshift, and gravitational waves. The concept of gravitational lensing is discussed as predicted by Einstein's general relativity theory. The formation of a gravitational lens can be observed when light from a bright distant source bends around a massive object between the source (such as a quasar) and the observer. Professor Bailyn then offers a slideshow of gravitational lenses. The issue of finding suitable astronomical objects that lend the opportunity to observe post-Newtonian relativistic effects is addressed. The lecture ends with Jocelyn Bell and the discovery of pulsars.

"Menjadi Pribadi Yang Bermanfaat Adalah Kemauan Kuncinya adalah kemauan, kemauan kita memberikan manfaat kepada orang lain. Jika kita punya harta, kita bisa memberikan manfaat kepada orang lain dengan harta. Jika kita punya ilmu, kita bisa memberikan manfaat ilmu kepada orang lain. Jika kita punya tenaga, kita bisa memberikan manfaat dari tenaga kita kepada orang lain."

Lecture 13 - Stellar Mass Black Holes (cont.)

 

 

 

 

 

 

Overview:

 

 

 

Class begins with clarification of equations from the previous lecture. Four post-Newtonian gravitational effects are introduced and discussed in detail. The first of these is the so-called Perihelion Precession, which occurs when the major axis of a planet's elliptical orbit precesses within its orbital plane, in response to changing gravitational forces exerted by other planets. Secondly, deflection of light is described as the curving of light as it passes near a large mass. Gravitational redshift is explained as a frequency effect that occurs as light moves away from a massive body such as a star or black hole. Finally, the existence and effects of gravitational waves are discussed. The lecture closes with a brief history of the 1919 eclipse expedition that made Einstein famous.
