Post-main-sequence planetary system evolution [PDF]
Royal Society Open Science, 2016 The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical

The saccade main sequence revised: A fast and repeatable tool for oculomotor analysis. [PDF]
Behav Res Methods, 2021 Saccades are rapid ballistic eye movements that humans make to direct the fovea to an object of interest. Their kinematics is well defined, showing regular relationships between amplitude, duration, and velocity: the saccadic ’main sequence’.

A planet within the debris disk around the pre-main-sequence star AU Microscopii. [PDF]
Nature, 2020 AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a distance of 9.79 parsecs and with an age of 22 million years 1 . AU Mic possesses a relatively rare 2 and spatially resolved 3 edge-on debris disk extending from about 35 to 210 ...

An inverse-linear logistic model of the main sequence [PDF]
Journal of Eye Movement Research, 2017 A model of the main sequence is proposed based on the logistic function. The model’s fit to the peak velocity-amplitude relation resembles an S curve, simulta- neously allowing control of the curve’s asymptotes at very small and very large amplitudes, as

A Main Sequence for Quasars [PDF]
Frontiers in Astronomy and Space Sciences, 2018 The last 25 years saw a major step forward in the analysis of optical and UV spectroscopic data of large quasar samples. Multivariate statistical approaches have led to the definition of systematic trends in observational properties that are the basis of

Speed-accuracy tradeoffs influence the main sequence of saccadic eye movements [PDF]
Scientific Reports, 2022 Several studies have proposed that an optimal speed-accuracy tradeoff underlies the stereotyped relationship between amplitude, duration and peak velocity of saccades (main sequence).

New evolutionary models for pre-main sequence and main sequence low-mass stars down to the hydrogen-burning limit [PDF]
, 2015 We present new models for low-mass stars down to the hydrogen-burning limit that consistently couple atmosphere and interior structures, thereby superseding the widely used BCAH98 models.

SDSS-IV MaNGA: Spatially Resolved Star Formation Main Sequence and LI(N)ER Sequence [PDF]
, 2017 We present our study on the spatially resolved Hα and M* relation for 536 star-forming and 424 quiescent galaxies taken from the MaNGA survey. We show that the star formation rate surface density ( ), derived based on the Hα emissions, is strongly ...

A Noninteracting Galactic Black Hole Candidate in a Binary System with a Main-sequence Star [PDF]
Astronomical Journal, 2022 We describe the discovery of a solar neighborhood (d = 468 pc) binary system with a main-sequence sunlike star and a massive noninteracting black hole candidate. The spectral energy distribution of the visible star is described by a single stellar model.

Surface Rotation and Photometric Activity for Kepler Targets. II. G and F Main-sequence Stars and Cool Subgiant Stars [PDF]
Astrophysical Journal Supplement Series, 2021 Dark magnetic spots crossing the stellar disk lead to quasiperiodic brightness variations, which allow us to constrain stellar surface rotation and photometric activity.
