An inverse-linear logistic model of the main sequence [PDF]

open access: yesJournal 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

Post-main-sequence planetary system evolution [PDF]

open access: yesRoyal 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

Speed-accuracy tradeoffs influence the main sequence of saccadic eye movements [PDF]

open access: yesScientific 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).

Blue Stragglers After the Main Sequence [PDF]

open access: yesThe Astrophysical Journal, 2008
We study the post-main sequence evolution of products of collisions between main sequence stars (blue stragglers), with particular interest paid to the horizontal branch and asymptotic giant branch phases.

Saccadic inhibition in a guided saccade task [PDF]

open access: yesPeerJ, 2018
The eye movement system reacts very systematically to visual transients that are presented during the planning phase of a saccade. About 50 to 70 ms after the onset of a transient, the number of saccades that are started decreases, a phenomenon that has ...

Photoevaporation and Close Encounters: How the Environment around Cygnus OB2 Affects the Evolution of Protoplanetary Disks

open access: yesThe Astrophysical Journal Supplement Series, 2023
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars. OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars ...

ABYSS. I. Targeting Strategy for the APOGEE and BOSS Young Star Survey in SDSS-V

open access: yesThe Astrophysical Journal Supplement Series, 2023
The fifth iteration of the Sloan Digital Sky Survey is set to obtain optical and near-infrared spectra of ∼5 million stars of all ages and masses throughout the Milky Way. As a part of these efforts, APOGEE and BOSS Young Star Survey (ABYSS) will observe

Near-core Acoustic Glitches Are Not Oscillatory: Consequences for Asteroseismic Probes of Convective Boundary Mixing

open access: yesThe Astrophysical Journal, 2023
Asteroseismology has been used extensively in recent years to study the interior structure and physical processes of main-sequence stars. We consider prospects for using pressure modes (p-modes) near the frequency of maximum oscillation power to probe ...

Simulating the Sensitivity to Stellar Point Sources of Chandra X-Ray Observations

open access: yesThe Astrophysical Journal Supplement Series, 2023
The Chandra Cygnus OB2 Legacy Survey is a wide and deep X-ray survey of the nearby and massive Cygnus OB2 association. The survey has detected ∼8000 X-ray sources, the majority of which are pre-main-sequence X-ray-emitting young stars in the association ...

On the Relationship of the Degrees of Correspondence of Dialects and Distances

open access: yesLanguages, 2019
This study analyzes the relationship between the degrees of resemblance and distances between dialects based on several dialectological atlases. This analysis investigates various correspondence data with respect to total valid data in setting reference ...
