From pulsating stars to transiting exoplanets, the search for periodic signals in K2 data, Kepler's 2-wheeled extension, is relevant to a long list of scientific goals. Systematics affecting K2 light curves due to the decreased spacecraft pointing precision inhibit the easy extraction of periodic signals from the data. We here develop a method for producing periodograms of K2 light curves that are insensitive to pointing-induced systematics; the Systematics-Insensitive Periodogram (SIP… 
Periodic transit and variability search with simultaneous systematics filtering: Is it worth it?
By using subsets of the HATNet and K2 (Kepler two-wheel) Campaign 1 databases, we examine the effectiveness of filtering out systematics from photometric time series while simultaneously searching
Agatha: disentangling periodic signals from correlated noise in a periodogram framework
It is found that Agatha outperforms other periodograms in terms of removing correlated noise and assessing the significances of signals with more robust metrics and can be used to select the optimal noise model and to test the consistency of signals in time.

New planetary and eclipsing binary candidates from campaigns 1−6 of the K2 mission
Context. With only two functional reaction wheels, Kepler cannot maintain stable pointing at its original target field and has entered a new mode of observation called K2. Aims. We describe a new
Systematics-insensitive Periodogram for Finding Periods in TESS Observations of Long-period Rotators
NASA's TESS mission \citep{tess} has produced high precision photometry of millions of stars to the community. The majority of TESS observations have a duration of $\approx$27 days, corresponding to
Synergies between exoplanet surveys and variable star research
With the discovery of the first transiting extrasolar planetary system back in 1999, a great number of projects started to hunt for other similar systems. Because the incidence rate of such systems
Are all RR Lyrae stars modulated?
We analyzed 151 variables previously classified as fundamental mode RR Lyrae stars from Campaigns 01–04 of the Kepler two-wheel (K2) archive. By employing a method based on the application of
The K2 Ecliptic Plane Input Catalog (EPIC) and Stellar Classifications of 138,600 Targets in Campaigns 1-8
The K2 Mission uses the Kepler spacecraft to obtain high-precision photometry over ~80 day campaigns in the ecliptic plane. The Ecliptic Plane Input Catalog (EPIC) provides coordinates, photometry
Planetary Candidates from the First Year of the K2 Mission
The Kepler Space Telescope is currently searching for planets transiting stars along the ecliptic plane as part of its extended K2 mission. We processed the publicly released data from the first year
Big Signals, Small Signals, Systematics
We examine the role of instrumental systematics in the search for small amplitude signal components in the presence of large amplitude signals. Current analyses of variable stars dealing with the


Precise time series photometry for the Kepler-2.0 mission
The recently approved NASA K2 mission has the potential to multiply by an order of magnitude the number of short-period transiting planets found by Kepler around bright and low-mass stars, and to
A Systematic Search for Transiting Planets in the K2 Data
This work applies a method for searching K2 light curves for evidence of exoplanets by simultaneously fitting for these systematics and the transit signals of interest, and presents posterior distributions on the properties of each system based strictly on the transit observables.
Kepler Presearch Data Conditioning II - A Bayesian Approach to Systematic Error Correction
With the unprecedented photometric precision of the Kepler spacecraft, significant systematic and stochastic errors on transit signal levels are observable in the Kepler photometric data. These

Measuring the rotation period distribution of field M dwarfs with Kepler
We have analysed 10 months of public data from the Kepler space mission to measure rotation periods of main-sequence stars with masses between 0.3 and 0.55 M_sun. To derive the rotational period we

This article introduces the completely new and significantly improved version of Presearch Data Conditioning (PDC) which was implemented in Kepler SOC version 8.0, which reliably corrects errors in the light curves while at the same time preserving planet transits and other astrophysically interesting signals.
We present a large sample of stellar rotation periods for Kepler Objects of Interest, based on three years of public Kepler data. These were measured by detecting periodic photometric modulation
