MBM 12: young protoplanetary discs at high galactic latitude

, 2009
(abridged) We present Spitzer infrared observations to constrain disc and dust evolution in young T Tauri stars in MBM 12, a star-forming cloud at high latitude with an age of 2 Myr and a distance of 275 pc.

Wind from T Tauri Stars [PDF]

Publications of the Astronomical Society of Japan, 1998
Previously, it was shown by DeCampli that an isothermal wind of T Tauri stars cannot explain both the mass-loss rates and X-ray observations. Since the assumption of an isothermal wind does not hold in general, we recalculated the structure of a steady and spherically symmetric stellar wind, taking the heating luminosity and its range as input ...

Haunting the Historiography of Slaves in South Asia from the nineteenth century to the present

Gender &History, EarlyView.
ABSTRACT Using both English and Urdu‐language records, this article traces the career of a few African and Afro‐Asian women slaves in the household‐state of Awadh during the first half of the nineteenth century. Focusing on the same records, this article compares a master‐poet's recognition of the motherhood of the African and Afro‐Asian slaves to the ...

Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate

, 2011
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity.

Exploring Brown Dwarf Disks [PDF]

, 2001
We discuss the spectral energy distribution of three very low mass objects in Chamaeleon I for which ground-based spectroscopy and photometry as well as ISO measurements in the mid-infrared are available (Comeron et al. 2000; Persi et al. 2000).

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, EarlyView.
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.

A Model of the C iv λ λ1548, 1550 Doublet Line in T Tauri Stars

The Astrophysical Journal
The C iv doublet in the UV has long been associated with accretion in T Tauri stars. However, it is still unclear where and how the lines are formed. Here, we present a new C iv line model based on the currently available accretion shock and accretion ...

A Two-Dimensional Near-Infrared Speckle Imaging Survey of T Tauri Stars in Taurus and Ophiuchus [PDF]

, 1992
We present the results of a magnitude limited (K≤8.5 mag) multiplicity survey of T Tauri stars in the two nearest star forming regions, Taurus-Auriga and Ophiuchus-Scorpius (D = 150 pc), observable from the northern hemisphere.

What Is Justice? Reflections on the Criminal Justice System in Brazil

The British Journal of Sociology, EarlyView.
ABSTRACT This essay explores the possibility of justice for the wretched of the earth. Using escrevivência (writing the experience/existence) and drawing on the theoretical insights and political praxis of the Assessoria Popular Maria Felipa (APMF, Maria Felipa Advocacy Group)—a Brazilian abolitionist organization led by Black activists—we analyze how ...
