Observations of Binary Stars with the Differential Speckle Survey Instrument. IX. Observations of Known and Suspected Binaries, and a Partial Survey of Be Stars
Elliott P. Horch, Gerard T. van Belle, James W. Davidson +13
We report 370 measures of 170 components of binary and multiple star systems, obtained from speckle imaging observations made with the Differential Speckle Survey Instrument at Low…
A hot terrestrial planet orbiting the bright M dwarf L 168-9 unveiled by TESS
N. Astudillo-Defru, R. Cloutier, S. X. Wang +67
We report the detection of a transiting super-Earth-sized planet (R=1.39+-0.09 Rearth) in a 1.4-day orbit around L 168-9 (TOI-134),a bright M1V dwarf (V=11, K=7.1) located at 25.15…
Observations of Binary Stars with the Differential Speckle Survey Instrument. VIII. Measures of Metal-Poor Stars and Triple Stars from 2015 to 2018
Elliott P. Horch, Andrei Tokovinin, Samuel A. Weiss +15
We present 248 speckle observations of 43 binary and 19 trinary star systems chosen to make progress in two main areas of investigation: the fundamental properties of metal poor st…
Observations of Binary Stars with the Differential Speckle Survey Instrument. VII. Measures from 2010 September to 2012 February at the WIYN Telescope
Elliott P. Horch, Dana I. Casetti-Dinescu, Matthew A. Camarata +9
We report on speckle observations of binary stars carried out at the WIYN Telescope over the period from September 2010 through February 2012, providing relative astrometry for 252…
Speckle Imaging Excludes Low-Mass Companions Orbiting the Exoplanet Host Star TRAPPIST-1
Steve B. Howell, Mark E. Everett, Elliott P. Horch +4
We have obtained the highest resolution images available of TRAPPIST-1 using the Gemini-South telescope and our speckle imaging camera. Observing at 692 and 883 nm, we reached the…
A Kinematically-Distinct RR-Lyrae Overdensity in the Inner Regions of the Milky Way
D. I. Casetti-Dinescu, D. A. Nusdeo, T. M. Girard +2
We combine the Siding Spring Survey of RR Lyrae stars with the Southern Proper Motion Catalog 4, in order to detect and kinematically characterize overdensities in the inner halo o…
