Robotic telescopes present the opportunity for the sparse temporal placement of observations when period searching. We address the best way to place a limited number of observations to cover the dynamic range of frequencies required by an observer. We show that an observation distribution geometrically spaced in time can minimise aliasing effects arising from sparse sampling, substantially improving signal detection quality. The base of the geometric series is however a critical factor in the… 
An autonomous adaptive scheduling agent for period searching
TLDR
The algorithm governing the behaviour of the agent uses an optimal geometric sampling technique to cover the period range of interest, but additionally implements proactive behaviour that maximises the optimality of the dataset in the face of an uncertain and changing operating environment.
Telescope Network Scheduling - Rationale and Formalisms
TLDR
This paper develops a formalism capable of expressing the complex requirements and preferences of astronomers concerning resource and time allocation on a telescope network, and formulates the offline telescope network scheduling problem as the problem of choosing and scheduling a maximum priority, non-overlapping subset of an input list of requests.
RADIAL VELOCITY PLANETS DE-ALIASED: A NEW, SHORT PERIOD FOR SUPER-EARTH 55 Cnc e
Radial velocity measurements of stellar reflex motion have revealed many extrasolar planets, but gaps in the observations produce aliases, spurious frequencies that are frequently confused with the
What do telescopes, databases, and compute clusters have in common?
TLDR
The current operations paradigm of the eSTAR network is presented and the direction of in which the project intends to develop over the next several years is described, including the challenges facing the project.
The abstract observatory: an interface for networking telescopes
TLDR
A generalised model for representing a telescope of arbitrary complexity as a networked resource that could be scheduled by a remote entity is discussed, using the SOAR 4.1m into the Las Cumbres Observatory (LCOGT) robotic telescope network.
Detectability of micro-variables in the ASAS database: the Scorpius-Centaurus Complex
TLDR
Nine years of photometry in the ASAS V-band catalogue is exploited to develop a method to select in an objective way the best quality data and detect low-amplitude variables, and the database contains much more information on photometric variables than retrieved commonly.
Spectral Analysis of Non-Uniformly Sampled Data: A New Approach Versus the Periodogram
We begin by revisiting the plain least-squares periodogram (LSP) for real-valued data. Then we introduce a new method for spectral analysis of non-uniformly sampled data by "iteratively weighting
OPTICAL IDENTIFICATION OF CEPHEIDS IN 19 HOST GALAXIES OF TYPE Ia SUPERNOVAE AND NGC 4258 WITH THE HUBBLE SPACE TELESCOPE
We present results of an optical search conducted as part of the SH0ES project (Supernovae and H0 for the Equation of State of dark energy) for Cepheid variable stars using the Hubble Space Telescope
A New Enhanced Method of Non Parametric power spectrum Estimation
TLDR
Of the existing methods for nonuniform sinusoidal data, Welch, MUSIC and ESPRIT methods appear to be the closest in spirit to the IAA proposed here, which makes use of the estimated covariance matrix that is computed in the first iteration of IAA from LSP.

Studies in astronomical time series analysis. II - Statistical aspects of spectral analysis of unevenly spaced data
TLDR
This paper studies the reliability and efficiency of detection with the most commonly used technique, the periodogram, in the case where the observation times are unevenly spaced to retain the simple statistical behavior of the evenly spaced case.

We present a photometric study of I-band variability in the young cluster IC 348. The main purpose of the study was to identify periodic stars. In all, we find 50 periodic stars, of which 32 were
