Syllabus
Prerequisites: Basic knowledge of general astronomy and physics.
Target skills and knowledge: The goal of this course is to give an advanced knowledge about observational issues and theoretical fundamentals in planetology and galactic and extragalactic astrophysics with respect to the basic and broad view given in the Bachelor Degree in Astronomy.
Examination methods: Oral exam about the topics discussed during lectures.
Assessment criteria: Knowledge of the topics presented during the lectures, quality and accuracy of the presentation, ability in making connections between the different topics and in comparing observations with theory.
Course unit contents: The first part is dedicated to instrumental techniques and observational aspects in photometry. One of the application is the instrumental and reddening corrections of the data. Then the interpretation of the near infrared color-magnitude and color-color diagrams of young stellar populations. The second part of the course is dedicated to the physical properties of the planets and to some basic concepts on the study of the extrasolar planets. The third part is a detailed analysis of emissions connected to the galactic interstellar medium evolution.
1) Basic concepts in astrophysics: magnitudes, distance modulus, metallicity indices. Distance measurements.
2) Signal-to-noise ratio of the observational data. Calibrations.
3) Interstellar reddening effects on the photometry.
4) Young stellar populations. HR diagrams and two color infrared diagrams.
5) General properties of the planets in the Solar System.
6) Atmosphere of the planets. Gas escape mechanisms.
7) Effective temperatures of the planets and greenhouse effect.
8) Origin and evolution of the Solar System. Urey and Lewis theory. Age of the Solar System. Formation of the Earth.
9) General characteristics of the planet Mars. Comparison with the Earth.
10) Basic principles of the extrasolar planets detection techniques.
11) The gas in the Galaxy. HI 21 cm line.
12) Supernovae remnants and basics of evolutionary models.
13) Stellar and interstellar maser sources.
Planned learning activities and teaching methods: Frontal lectures with the use of blackboard, slides and PowerPoint presentations. Lectures are given in Italian.
Additional notes about suggested reading: Lecture notes provided by the teacher and available through the Moodle website of the course on the e-learning platform of the Department of Physics and Astronomy "G. Galilei" (https://elearning.unipd.it/dfa/). Scientific papers about some specific topics are also available as additional material.
