THE STARS OF THE LOWER PART OF MAIN SEQUENCE
Odessa Astronomical Publications, 2007 Atmospheric parameters (Teff , log g, [Fe/H], Vt), Li, and volatile (O, Na, Al, Zn) and refractory (Si, Ti, V, Cr, Co and Ni) element abundances in 133 stars belonging to the low part of MS have been determined. Among them about 30 stars are the variable

Saccadic inhibition in a guided saccade task [PDF]
PeerJ, 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 ...

The 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 ...

The main sequence of quasars: The taming of the extremes [PDF]
Astronomische Nachrichten, 2021 AbstractThe last few years have seen the confirmation of several trends associated with the quasar main sequence. The idea of a main sequence for quasars is relatively recent, and its full potential for the observational classification and contextualization of quasars' properties has yet to be fully exploited. The main sequence drivers are discussed in

The 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 ...

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

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