Rotation effects in classical T Tauri stars [PDF]
Astronomy Letters, 2012 Surface temperature inhomogeneities in classical T Tauri stars (CTTS) induced by magnetic activity and mass accretion lead to rotational modulation of both photometric and spectroscopic parameters of these stars. Using the extended photometric catalogue by Grankin et al. (2007), we have derived the periods and amplitudes of the rotational modulation of

Inclination effects in T Tauri star spectra [PDF]
, 2013 Context. Because of the presence of rotation and accretion disks, classical T Tauri stars have symmetry planes that are normally inclined relative to the plane of the sky. The inclination angles affect the observed spectral properties

Haro 5-2: A New Pre-main-sequence Quadruple Stellar System
The Astronomical JournalWe have discovered that the H α emission-line star Haro 5-2, located in the 3–6 Myr old Ori OB1b association, is a young quadruple system. The system has a 2+2 configuration, with an outer separation of 2.″6 and with resolved subarcsecond inner binary ...

Child &Family Social Work, Volume 31, Issue 4, Page 2315-2326, November 2026.ABSTRACT Safeguarding Family Group Conferencing (FGC) is a family‐led decision‐making process offered to some families in England as an alternative to an Initial Child Protection Conference when Children's Services have safeguarding concerns. A realist evaluation was conducted within three local authorities piloting this approach to build understanding

The Variability of the T Tauri Star DI Cephei [PDF]
International Astronomical Union Colloquium, 1983 Abstract:It is demonstrated that the light variations of DI Cephei can be explained as due to the combined effect of variable completely grey circumstellar extinction and variable continuous and line emission.

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950
Gender &History, Volume 38, Issue 3, Page 859-869, October 2026.ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Magnetic Fields and Planets of Weak-line T Tauri Stars
, 2018 T-Tauri stars are late-type pre-main-sequence stars that are gravitationally contracting towards the main sequence. Magnetic fields largely dictate the angular momentum evolution of these stars and can affect the formation and migration of planets. Thus,

Hot H2O emission during an outburst in a classical T Tauri star
Astronomy & AstrophysicsContext. The unstable mass accretion process in young stellar objects (YSOs) often triggers observable outbursts. These episodic accretion events play a critical role in stellar mass assembly during the pre-main-sequence phase.

Who Is a Patriotic Man? Rethinking Hegemonic Masculinity in Modern Iran
Gender &History, Volume 38, Issue 3, Page 846-858, October 2026.ABSTRACT This article examines the analytical viability of the concept of “hegemonic masculinity” in the historical study of masculinities in early‐twentieth‐century Iran (c.1890–1941). It argues that a radical problematizing of the concepts of hegemony, class, “the West,” and patriotism helps us move beyond the binaries of Western‐Iranian and modern ...
