Predicting the time variation of radio emission from MHD simulations of a flaring T-Tauri star
We model the time dependent radio emission from a disk accretion event in aT-Tauri star using 3D, ideal magnetohydrodynamic simulations combined with agyrosynchrotron emission and radiative transfer model.

SPECTRAL AND PHOTOMETRIC RESEARCHES OF RY TAU
Odessa Astronomical Publications, 2010 The results of analysis of the total light curve of the classic T Tauri type star RY Tau were presented. For a time at last 48 years a brightness of the star is characterized by fluctuations with amplitude about ΔV ∼1m, with characteristic time about 300

Travelling, Staying, Working, Imagining: Space and the Practice of Internationalism, c1900–1950
History Compass, Volume 24, Issue 5, October 2026.ABSTRACT This article considers space as a key element in the practice of internationalism in the first half of the 20th century. Drawing on approaches in historical geography and cultural history, the article proposes four analytical categories through which internationalism might be explored in the period between 1900 and 1950.

A Tale of Two Stars: X-Ray and Ground-based Observations of Two Diverging Stars in Taurus–Auriga
The Astrophysical JournalWe present XMM-Newton observations and near-simultaneous optical observations of the classical T Tauri star SU Auriga and the nearby Herbig Ae star AB Auriga, two members of the 4 Myr old Taurus–Auriga star-forming region.

MHD Simulations of Magnetized Stars in the Propeller Regime of Accretion
EPJ Web of Conferences, 2014 Accreting magnetized stars may be in the propeller regime of disc accretion in which the angular velocity of the stellar magnetosphere exceeds that of the inner disc.

The Türkiye‐Qatar Partnership: From Ottoman Roots to Strategic Alliance
Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.Abstract As Qatar, a small country in a strategic location, faced a pressure campaign from Gulf states in 2017, Türkiye expanded its military presence and provided support that proved crucial to Doha's ability to overcome the crisis. This demonstrated Türkiye's new grand strategy, its capacity to project influence into the Gulf, and its status as a ...

The effect of variable stellar magnetic fields on the spin state of T Tauri stars
Astronomy & AstrophysicsUnderstanding the stellar spin evolution of young stars is crucial for understanding the evolution of protoplanetary disks and, consequently, the formation of exoplanets.

Rethinking Political Islam in Iran: Contestation, Authority, and Reform
Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.Abstract Political Islam in Iran is frequently portrayed in Western scholarship and policy discourse as a unified and rigid ideological system rooted in the 1979 Islamic Revolution. However, this article contends that it operates as a plural and internally contested field in which state‐directed, reformist‐clerical, and civic interpretations compete ...
