SHIMM: A Versatile Seeing Monitor for Astronomy
Saavidra Perera, Richard W. Wilson, Tim Butterley +3
Characterisation of atmospheric optical turbulence is crucial for the design and operation of modern ground-based optical telescopes. In particular, the effective application of ad…
Estimating effective wind speed from Gemini Planet Imager's adaptive optics data using covariance maps
Daniel M. Levinstein, Saavidra Perera, Quinn M. Konopacky +4
The Earth's turbulent atmosphere results in speckled and blurred images of astronomical objects when observed by ground based visible and near-infrared telescopes. Adaptive optics…
Limitations imposed by optical turbulence profile structure and evolution on tomographic reconstruction for the ELT
O. J. D. Farley, J. Osborn, T. Morris +4
The performance of tomographic adaptive optics systems is intrinsically linked to the vertical profile of optical turbulence. Firstly, a sufficient number of discrete turbulent lay…
Characterisation of the ground layer of turbulence at Paranal using a robotic SLODAR system
T. Butterley, R. W. Wilson, M. Sarazin +3
We describe the implementation of a robotic SLODAR instrument at the Cerro Paranal observatory. The instrument measures the vertical profile of the optical atmospheric turbulence s…
The Type II-Plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor
Schuyler D. Van Dyk, WeiKang Zheng, Justyn R. Maund +31
We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 20…
The PDS 110 observing campaign - photometric and spectroscopic observations reveal eclipses are aperiodic
Hugh P. Osborn, Matthew Kenworthy, Joseph E. Rodriguez +71
PDS 110 is a young disk-hosting star in the Orion OB1A association. Two dimming events of similar depth and duration were seen in 2008 (WASP) and 2011 (KELT), consistent with an ob…
