Occurrence and Architecture of Kepler Planetary Systems as Functions of Stellar Mass and Effective Temperature [PDF]

open access: yesAstronomical Journal, 2020
The Kepler mission has discovered thousands of exoplanets around various stars with different spectral types (M, K, G, and F) and thus different masses and effective temperatures.

Planetary Candidates Observed by Kepler IV: Planet Sample From Q1-Q8 (22 Months) [PDF]

open access: yes, 2013
We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 Threshold Crossing Events (TCEs), 480 new host stars are identified from their flux ...

Elementary Solution of Kepler Problem (and a few other problems)

open access: yesRevista Brasileira de Ensino de Física, 2022
We present a simple method to obtain the solution of a few orbital problems: the Kepler problem, the modified Kepler problem by the addition of an inverse square potential and linear force.

Kepler Data Validation I—Architecture, Diagnostic Tests, and Data Products for Vetting Transiting Planet Candidates [PDF]

open access: yes, 2018
The Kepler Mission was designed to identify and characterize transiting planets in the Kepler Field of View and to determine their occurrence rates. Emphasis was placed on identification of Earth-size planets orbiting in the Habitable Zone of their host ...

The Flare Catalog and the Flare Activity in the Kepler Mission [PDF]

open access: yesAstrophysical Journal Supplement Series, 2019
We present a flare catalog of the Kepler mission using the long-cadence data of Data Release 25. This catalog comprises 3420 flare stars and 162,262 flare events.

RR Lyrae Stars as Seen by the Kepler Space Telescope

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The unprecedented photometric precision along with the quasi-continuous sampling provided by the Kepler space telescope revealed new and unpredicted phenomena that reformed and invigorated RR Lyrae star research.

Architectures of exoplanetary systems – I. A clustered forward model for exoplanetary systems around Kepler’s FGK stars [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
Observations of exoplanetary systems provide clues about the intrinsic distribution of planetary systems, their architectures, and how they formed. We develop a forward modelling framework for generating populations of planetary systems and ‘observed ...

Asteroseismology of 16,000 Kepler Red Giants: Global Oscillation Parameters, Masses, and Radii [PDF]

open access: yesAstrophysical Journal Supplement Series, 2018
The Kepler mission has provided exquisite data to perform an ensemble asteroseismic analysis on evolved stars. In this work we systematically characterize solar-like oscillations and granulation for 16,094 oscillating red giants, using end-of-mission ...

Long-Period Giant Companions to Three Compact, Multiplanet Systems [PDF]

open access: yes, 2019
Understanding the relationship between long-period giant planets and multiple smaller short-period planets is critical for formulating a complete picture of planet formation. This work characterizes three such systems. We present Kepler-65, a system with
