Wind from T Tauri Stars [PDF]

open access: yesPublications 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 ...

Which jet launching mechanism(s) in T Tauri stars [PDF]

open access: yes, 2006
Aims. We examine whether ejection phenomena from accreting T Tauri stars can be described by only one type of self-collimated jet model. Methods. We present analytical kinematic predictions valid soon after the Alfven surface for all types of steady ...

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

open access: yesGender &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 ...

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

open access: yesThe 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 ...

Measuring the Dust Masses of Protoplanetary Disks in Lupus with ALMA: Evidence That Disks Can Be Optically Thick at 3 mm

open access: yesThe Astrophysical Journal, 2022
Accurate disk mass measurements are necessary to constrain disk evolution and the timescale of planet formation, but such measurements are difficult to make and are very dependent on assumptions. Here, we look at the assumption that the disk is optically

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

open access: yesGender &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.

ACCRETION RATES FOR T TAURI STARS USING NEARLY SIMULTANEOUS ULTRAVIOLET AND OPTICAL SPECTRA [PDF]

open access: yes, 2013
We analyze the accretion properties of 21 low-mass T Tauri stars using a data set of contemporaneous near-UV (NUV) through optical observations obtained with the Hubble Space Telescope Imaging Spectrograph and the ground-based Small and Medium Aperture ...

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

open access: yesThe 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 ...
