The frequency of T Tauri companion stars [PDF]

open access: yes, 1993
We present the results of a magnitude limited (K≤8.5 mag) multiplicity survey of T Tauri stars in two nearby star forming regions, Tauris-Auriga and Ophiuchus-Scorpius.

Bovine Viral Diarrhoea Virus Across Asia: A Systematic Review and Meta‐Analysis of Prevalence in Cattle Population Between 2000 and 2025

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This systematic review and meta‐analysis summarize the epidemiology of bovine viral diarrhoea virus (BVDV) infection in cattle populations across Asia. Analysis of 133 studies comprising 160,042 cattle revealed a pooled seroprevalence of 40.50% and a pooled antigen prevalence of 9.0% (44,636 cattle). These findings provide an extensive synthesis of the

Gendering Late Ottoman Society and Reconstructing Gender in the Women's Press

open access: yesGender &History, Volume 38, Issue 2, Page 580-595, July 2026.
ABSTRACT This article analyses the construction of gender differences in the late Ottoman Empire through women's periodicals, which acted as a key medium in the redefinition of gender roles. It examines how new understandings of gender roles emerged amid rapid transformations in traditional societal structures, particularly in the women’s press.

Dispersed T Tauri stars and galactic star formation

open access: yesAIP Conference Proceedings, 1996
The spatial distribution, age distribution and kinematics of T Tauri stars, both close to and widely distributed around active clouds, are considered using simple models of T Tauri dispersal. Models are compared to observations in and around the nearby cloud complexes, in particular the recent discovery of widely scattered young stars from the ROSAT ...

Are T Tauri stars gamma-ray emitters? [PDF]

open access: yes, 2019
T Tauri stars are young, low-mass, pre-main-sequence stars surrounded by an accretion disk. These objects present strong magnetic activity and powerful magnetic reconnection events.

New “weak-line"–T Tauri stars in Lupus

open access: yes, 1997
We present first results obtained by a survey of the Lupus star forming region in search of new T Tauri stars. This study has been performed on the basis of deep pointed ROSAT observations in the Lupus dark clouds as well as data from the ROSAT All ...

The circumstellar environment of the young, low-mass dipper star JH 223

open access: yesAstronomy & Astrophysics
Context. Studies of magnetospheric accretion and magnetic field topology in T Tauri stars have advanced over the years, but their applications to fully convective, very-low-mass T Tauri stars remain relatively unexplored. Aims.

Weak-line T Tauri stars: circumstellar disks and companions

open access: yes, 2005
We have analysed new infrared photometric data taken by the Infrared Space Observatory, in combination with 2MASS data where available, of 12 weak-line T Tauri stars (WTTS), belonging to different molecular clouds.

The enviroments of T Tauri stars

open access: yesThe Astrophysical Journal, 1983
The environments of T Tauri stars are probably determined by the interaction of a stellar wind with matter which is falling toward a newly formed star. As shown by Ulrich, the steady infall of cool gas with angular momentum toward the star leads to a density distribution with rhoproportionalr/sup -1/2/ inside a radius r/sub d/ and rhoproportionalr/sup -
