Study of Vibrations at SOAR
Andrei Tokovinin
The 4.1-m Southern Astrophysics Research (SOAR) telescope in Chile resembles larger optical telescopes by its thin actively controlled primary mirror, built-in tip-tilt correction,…
Operational capabilities and on-sky performance of SAMOS at the completion of science commissioning
Massimo Robberto, Stephen A. Smee, Robert H. Barkhouser +9
We present the operational capabilities and on-sky performance of the SOAR Adaptive Module Optical Spectrograph (SAMOS) at the completion of its science commissioning phase. SAMOS…
Performance of the Southern Astrophysical Research Telescope Speckle Instrument
Andrei Tokovinin
The High Resolution Camera (HRCam) speckle imager at the 4.1 m Southern Astrophysical Research telescope is a highly productive instrument that has accumulated about 40K observatio…
High-resolution imaging at the SOAR telescope
A. Tokovinin, R. Cantarutti, R. Tighe +4
Bright single and binary stars were observed at the 4.1-m telescope with a fast electron-multiplication camera in the regime of partial turbulence correction by the visible-light a…
Donut: measuring optical aberrations from a single extra-focal image
A. Tokovinin, S. Heathcote
We propose a practical method to calculate Zernike aberrations from analysis of a single long-exposure defocused stellar image. It consists in fitting the aberration coefficients a…
