A Comprehensive Analysis of Rovibrational CO in the Era of JWST

The Astronomical Journal
We present an analysis of CO rovibrational emission lines in the 183 infrared spectra of nearby Class II objects obtained with the NIRSPEC instrument on the Keck II telescope over the past two decades.

Large Myr-old Disks Are Not Severely Depleted of Gas-phase CO or Carbon

The Astrophysical Journal, 2023
We present an ACA search for [C i ] 1–0 emission at 492 GHz toward large T Tauri disks (gas radii ≳ 200 au) in the ∼1–3 Myr-old Lupus star-forming region. Combined with Atacama Large Millimeter/submillimeter Array 12 m archival data for IM Lup, we report

Nature's Ambiguous Sex: The Body as a Feminist Resource in German Naturism Around 1900

Gender &History, EarlyView.
ABSTRACT While gender relations around 1900 were generally marked by sharp dichotomies grounded in nature and the body, the case of naturism appears paradoxical. An influential movement in Germany, it promoted a reform of the body according to natural principles.

Variability of the transitional T Tauri star T Chamaeleontis [PDF]

Astronomy & Astrophysics, 2009
We characterize the physical properties of T Chamaeleontis, a transitional T Tauri star showing UX Ori-type variability, and of its associated disc, and probe possible effects of disc clearing processes. Different spectral diagnostics are examined, based on a rich collection of optical high- and low-resolution spectra. We determine radial and projected

THE PTF orion project: a possible planet transiting a T-Tauri star

, 2012
We report observations of a possible young transiting planet orbiting a previously known weak-lined T-Tauri star in the 7–10 Myr old Orion-OB1a/25-Ori region. The candidate was found as part of the Palomar Transient Factory (PTF) Orion project.

Respected and Ignored: British Women and the Arab Revolt (1936–39) in Mandate Palestine

Gender &History, EarlyView.
ABSTRACT This article aims to reinsert British women and their perspectives into our understanding of anticolonial resistance in Palestine. Historiography on the Arab Revolt (1936–39) has previously been built from colonial state archives that disproportionally speak with a male voice and, as such, rely on certain gendered assumptions to describe the ...

The Spectral Variability of the T Tauri Star DF Tauri [PDF]

The Astrophysical Journal, 1997
We analyze 117 echelle spectra of the T Tauri star DF Tau, concentrating on variations in the optical continuum veiling and the strong emission lines. Although this star was the inspiration for the original suggestion of magnetospheric accretion in T Tauri stars (TTSs), this hypothesis is only partially supported in our data. We find that variations in

Unstable magnetospheric accretion on the T Tauri star TW Hya

Astronomy & Astrophysics
In this paper, we present new spectropolarimetric and velocimetric observations of the prototypical classical T Tauri star TW Hya obtained with SPIRou at the Canada-France-Hawaii Telescope, expanding our previous monitoring over two new seasons (2024 and

Analysis of star-disk interaction in young stellar systems

EPJ Web of Conferences, 2014
We present preliminary results of the study of star-disk interaction in the classical T Tauri star V354 Mon, a member of the young stellar cluster NGC 2264.

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 ...
