学位要求
The Departments of Astronomy and Physics each offer programs of research in astronomy and astrophysics leading to the Ph.D. degree. The degrees of Master of Arts and Master of Philosophy in Astronomy may also be obtained after one or more years of course work, but students are not normally admitted to pursue these degrees only. Advanced standing can be granted for students admitted with post-bachelor’s degrees, based on 个人评价。
哲学程序
The PhD is awarded for independent, original research. As such, it is qualitatively different from all other degrees and, for most students, from anything they have encountered in their first sixteen years of education, where the knowledge base was already established, the choice of topics was the teacher’s, and success was defined 通过 achievement on 论文和考试。
With this in mind, the Columbia Astronomy program emphasizes original research, commencing the very first week new students arrive in 晨。
First and Second Year Projects
每年开始 astrofest,
a day where each faculty, post-doc, and current graduate student presents
a talk or poster explaining their research (accompanied 通过 a generous
allocation of comestibles and libations). The following week, first-year
students participate in a series of one-hour meetings as a group with each
faculty member designed to showcase the range of research projects
available; all students then choose a
Over the course of the first two years and the two summers following them, students are expected to complete at least two research projects, each with a different faculty member in a different area of 天文学。 Both a written report (either an article for publication or something written in the same style) and an oral presentation on the project results are due each 九月。
Many students submit results from their research for publication in professional journals. Instead of a traditional qualifying exam, research exams are held at the completion of the first and second year. Our course requirements are designed to impart the knowledge necessary for research in 天文学。
Often, one of these projects then evolves into the dissertation project, a written proposal presented in the first semester of the third year. A three-member faculty committee is assigned to each student to monitor his or her progress throughout the student’s time here at Columbia.
当然工作
Coursework includes five required graduate courses plus three additional electives in Astronomy, Physics, or some other department in the 毕业 School. The required courses are
- 天文6001 辐射过程
- 天文6002 The Interstellar and Intergalactic Media
- 天文6003 恒星和星系动力学
- 天文6004 Stellar Structure and Evolution
- 天文6005 物理宇宙学
By the end of the second year, it is expected that students will have completed the Master’s course requirements which includes the 30 points of graduate credit and the two years of residence as a full-time student in the program. Students entering with a Master’s degree may be granted advanced standing depending on their performance; this action waives the point and residence units requirements, although most such students still take courses from the curriculum.

In order to facilitate their rapid transition to our research-intensive program, first-year students are not expected to teach a Lab section. However, in order to
All second-year students are normally expected to teach one section per semester of Laboratory C1903/1904 (comprising a small class of 10-12 undergraduates). They are
