Observing the Sun as a star: Design and early results from the NEID solar feed
Andrea S. J. Lin, Andrew Monson, Suvrath Mahadevan +27
Efforts with extreme-precision radial velocity (EPRV) instruments to detect small-amplitude planets are largely limited, on many timescales, by the effects of stellar variability a…
ISPY -- NaCo Imaging Survey for Planets around Young stars. CenteR: the impact of centering and frame selection
N. Godoy, J. Olofsson, A. Bayo +18
Abridged: Direct imaging has made significant progress over the past decade leading to the detection of several giant planets. Observing strategies and data rates vary from instrum…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Cosmic-Ray-Related Signals from Detectors in Space: the Spitzer/IRAC Si:As IBC Devices
Brendan Hagan, George Rieke, Ori D. Fox +4
We evaluate the hit rate of cosmic rays and their daughter particles on the Si:As IBC detectors in the IRAC instrument on the Spitzer Space Telescope. The hit rate follows the ambi…
Wavelength Calibration and Resolving Power of the JWST MIRI Medium Resolution Spectrometer
A. Labiano, I. Argyriou, J. Alvarez-Marquez +13
The Mid-Infrared Instrument (MIRI) on-board JWST will provide imaging, coronagraphy, low-resolution spectroscopy and medium-resolution spectroscopy at unprecedented sensitivity lev…
The TESS Mission Target Selection Procedure
Michael Fausnaugh, Ed Morgan, Roland Vanderspek +61
We describe the target selection procedure by which stars are selected for 2-minute and 20-second observations by TESS. We first list the technical requirements of the TESS instrum…
