Measuring Transit Signal Recovery in the Kepler Pipeline. III. Completeness of the Q1-Q17 DR24 Planet Candidate Catalogu...
...
Published in The Astrophysical Journal
With each new version of the Kepler pipeline and resulting planet candidate catalogue, an updated measurement of the underlying planet population can only be recovered with an corresponding measurement of the Kepler pipeline detection efficiency. Here, we present measurements of the sensitivity of the pipeline (version 9.2) used to generate the Q1-...
Detection of Potential Transit Signals in 17 Quarters of Kepler Data: Results of the Final Kepler Mission Transiting Pla...
...
Published in arXiv preprint arXiv:1604.06140
We present results of the final Kepler Data Processing Pipeline search for transiting planet signals in the full 17-quarter primary mission dataset. The search includes a total of 198,709 stellar targets of which 112,046 were observed in all 17 quarters and 86,663 in fewer than 17 quarters. We report on 17,230 targets for which at least one transit...

...Published in arXiv preprint arXiv:1512.06149
We present the seventh Kepler planet candidate catalog, which is the first to be based on the entire, uniformly processed, 48 month Kepler dataset. This is the first fully automated catalog, employing robotic vetting procedures to uniformly evaluate every periodic signal detected by the Q1-Q17 Data Release 24 (DR24) Kepler pipeline. While we priori...

Prospects for Integrating a Hollow Electron Lens into the LHC Collimation System US Particle Accelerator Conference Trap...
Published in Proceedings of PAC09, Vancouver, BC, Canada
It has been proposed to use a hollow electron lens with the LHC beam collimation system [1]. The hollow electron beam would be used as a beam scraper and positioned at a closer sigma than the primary collimators to increase the halo particle diffusion rate striking the primaries. In this paper we use multi-turn beam tracking simulations to analyze ...
Mechanical and thermal Prototype Testing for a Rotatable Collimator for the LHC Phase II Collimation Upgrade
Published in Part of Particle accelerator. Proceedings, 11th European Conference, EPAC 2008, Genoa, Italy
The Phase II upgrade to the LHC collimation system calls for complementing the robust Phase I graphite collimators with high Z, low impedance Phase II collimators. The design for the collimation upgrade has not been finalized. One option is to use metallic rotatable collimators and testing of this design will be discussed here. The Phase II colli...

Planetary Candidates Observed by V: Planet Sample from Q1-Q12 (36 Months)
...Published in arXiv preprint arXiv:1501.07286
The Kepler mission discovered 2842 exoplanet candidates with 2 years of data. We provide updates to the Kepler planet candidate sample based upon 3 years (Q1-Q12) of data. Through a series of tests to exclude false-positives, primarily caused by eclipsing binary stars and instrumental systematics, 855 additional planetary candidates have been disco...

Finding Every Planet We Can – Improving the Optimal Apertures in Kepler Data " Towards Other Earths II, The Star Planet ...
With the loss of two spacecraft reaction wheels precluding further data collection in the primary mission, even greater pressure is placed on the processing pipeline to eke out every last transit signal in the data. To that end, we have developed a new method to optimize the Kepler Simple Aperture Photometry photometric apertures for both plan...

Kepler Data Release 21 Notes (KSCI-19061-001)
...Published in Kepler mission
These Data Release Notes provide information specific to the current reprocessing and re-export of Q0–Q14 data. Specifically, this data release provides an improved version of the PDC light curves and corrects the barycentric times so they include the conversion to TDB (Barycentric Dynamical Time). As such, these Notes are an addendum to the Data R...
Constraints, Approach and Present Status for Selecting the Mars Surveyor 2001 Landing Site

There are many similarities between the Mars Surveyor 01 (MS 01) landing site selection process and that of Mars Pathfinder. The selection process includes two parallel activities in which engineers define and refine the capabilities of the spacecraft through design, testing and modeling and scientists define a set of landing site constraints based...
