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

open access: goldScientific 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).

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

A timing formula for main-sequence star binary pulsars [PDF]

open access: bronze, 1998
In binary radio pulsars with a main-sequence star companion, the spin-induced quadrupole moment of the companion gives rise to a precession of the binary orbit.

A Main Sequence for Quasars [PDF]

open access: yesFrontiers 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

Pre-main-sequence Lithium Depletion [PDF]

open access: yes, 2004
In this review I briefly discuss the theory of pre-main-sequence (PMS) Li depletion in low-mass (0 ...

Determining the main-sequence mass of Type II supernova progenitors [PDF]

open access: bronze, 2010
We present radiation-hydrodynamics simulations of core-collapse supernova (SN) explosions, artificially generated by driving a piston at the base of the envelope of a rotating or non-rotating red-supergiant progenitor star. We search for trends in ejecta

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 ...
