Studying bright variable stars with the Multi-site All-Sky CAmeRA (MASCARA)
O. Burggraaff, G. J. J. Talens, J. Spronck +6
The Multi-site All-Sky CAmeRA (MASCARA) aims to find the brightest transiting planet systems by monitoring the full sky at magnitudes , taking data every 6.4 seconds. The…
MASCARA-1 b: A hot Jupiter transiting a bright A-star in a misaligned orbit
G. J. J. Talens, S. Albrecht, J. F. P. Spronck +11
We report the discovery of MASCARA-1 b, the first exoplanet discovered with the Multi-site All-Sky CAmeRA (MASCARA). It is a hot Jupiter orbiting a bright , rapidly rotati…
MASCARA-2 b: A hot Jupiter transiting the A-star HD185603
G. J. J. Talens, A. B. Justesen, S. Albrecht +13
In this paper we present MASCARA-2 b, a hot Jupiter transiting the A2 star HD 185603. Since early 2015, MASCARA has taken more than 1.6 million flux measurements of the s…
The Multi-site All-Sky CAmeRA: Finding transiting exoplanets around bright () stars
G. J. J. Talens, J. F. P. Spronck, A. -L. Lesage +4
This paper describes the design, operations, and performance of the Multi-site All-Sky CAmeRA (MASCARA). Its primary goal is to find new exoplanets transiting bright stars, $4 < m_…
HARPS3 for a Roboticized Isaac Newton Telescope
Samantha J. Thompson, Didier Queloz, Isabelle Baraffe +25
We present a description of a new instrument development, HARPS3, planned to be installed on an upgraded and roboticized Isaac Newton Telescope by end-2018. HARPS3 will be a high r…
Fiber scrambling for high-resolution spectrographs. II. A double fiber scrambler for Keck Observatory
Julien F. P. Spronck, Debra A. Fischer, Zachary Kaplan +4
We have designed a fiber scrambler as a prototype for the Keck HIRES spectrograph, using double scrambling to stabilize illumination of the spectrometer and a pupil slicer to incre…
The Twenty-Five Year Lick Planet Search
Debra A. Fischer, Geoffrey W. Marcy, Julien F. P. Spronck
The Lick planet search program began in 1987 when the first spectrum of Ceti was taken with an iodine cell and the Hamilton Spectrograph. Upgrades to the instrument improved th…
CHIRON - A Fiber Fed Spectrometer for Precise Radial Velocities
Andrei Tokovinin, Debra A. Fischer, Marco Bonati +5
The CHIRON optical high-resolution echelle spectrometer was commissioned at the 1.5m telescope at CTIO in 2011. The instrument was designed for high throughput and stability, with…
Fiber scrambling for high-resolution spectrographs. I. Lick Observatory
Julien F. P. Spronck, Debra A. Fischer, Zachary A. Kaplan +2
In this paper, we report all results obtained with a fiber scrambler on the Hamilton spectrograph at Lick Observatory. We demonstrate an improvement in the stability of the instrum…
Planet Hunters: The First Two Planet Candidates Identified by the Public using the Kepler Public Archive Data
Debra Fischer, Megan Schwamb, Kevin Schawinski +28
Planet Hunters is a new citizen science project, designed to engage the public in an exoplanet search using NASA Kepler public release data. In the first month after launch, users…
A High Eccentricity Component in the Double Planet System Around HD 163607 and a Planet Around HD 164509
Matthew J. Giguere, Debra A. Fischer, Andrew W. Howard +7
We report the detection of three new exoplanets from Keck Observatory. HD 163607 is a metal-rich G5IV star with two planets. The inner planet has an observed orbital period of 75.2…
M2K: II. A Triple-Planet System Orbiting HIP 57274
Debra A. Fischer, Eric Gaidos, Andrew Howard +14
Doppler observations from Keck Observatory have revealed a triple planet system orbiting the nearby mid-type K dwarf, HIP 57274. The inner planet, HIP 57274b, is a super-Earth with…
The California Planet Survey III. A Possible 2:1 Resonance in the Exoplanetary Triple System HD 37124
J. T. Wright, Dimitri Veras, Eric B. Ford +8
We present new radial velocities from Keck Observatory and both Newtonian and Keplerian solutions for the triple-planet system orbiting HD 37124. The orbital solution for this syst…
