All HS students --------------- - Brief introductions of the HS students and mentors (all HS students) - Discussion of end of summer presentations / papers for science competitions in the fall and next spring (all HS students) Astronomy & instrumentation HS students --------------------------------------- - One week participation in Quarknet in early August - Events calendar Astronomy HS students --------------------- - Unix, IDL, accessing the UCSC computers (remote, wireless, vs wired) - Accessing astronomy journal articles: NASA/ADS -> http://adsabs.harvard.edu/abstract_service.html arXiv -> http://xxx.lanl.gov/form/astro-ph - Use of office space (ISB 356, ISB 2nd and 3rd floor common areas, CfAO common areas, etc) - Basic astronomical concepts: . RA/DEC coordinates - Reversed parity wrt longitude/latitude - Hours/min/sec of time vs degrees/min/sec of arc - RA is generally along small circles - cos(DEC) factor . Telescopes and instruments - Focusing light - cameras, spectrographs . Images and photometry - Point spread function - Meaning of magnitudes . Spectroscopy - Spectrum = series of images - Sky subtraction - Absorption/emission lines - relation to atomic physics - Doppler shift: radial velocity, redshift (distance in the context of expanding Universe) - Transverse velocities are difficult to measure
