The Kinematics and Excitation of Infrared Water Vapor Emission from Planet-forming Disks: Results from Spectrally Resolved Surveys and Guidelines for JWST Spectra

open access: yesThe Astronomical Journal, 2023
This work presents ground-based spectrally resolved water emission at R = 30,000–100,000 over infrared wavelengths covered by the JWST (2.9–12.8 μ m). Two new surveys with iSHELL and the VISIR are combined with previous spectra from the CRIRES to cover ...

Observational clues for a role of circumstellar accretion in PMS X-ray activity [PDF]

open access: yes, 2002
We revisit the published analyses of ROSAT X-ray observations of the star forming regions NGC 2264 and Chamaeleon I (~3 and ~5 Myr old respectively) in the light of newly published optical data.

COSMOPOLITAN PHILOLOGY AND SACRED GRAMMAR

open access: yesHistory and Theory, Volume 64, Issue 4, Page 109-126, December 2025.
ABSTRACT Persian developed a formal grammatical tradition comparatively late in its thousand‐year history as a lingua franca. This article takes up the emergence of Persian grammar within the larger trajectory of Persian philology. It explores questions about why and when such a tradition developed in Persian by closely analyzing the earliest formal ...

Assessment of genetically modified oilseed rape LBFLFK (application EFSA‐GMO‐DE‐2019‐157)

open access: yesEFSA Journal, Volume 23, Issue 11, November 2025.
Abstract Application EFSA‐GMO‐DE‐2019‐157 (oilseed rape LBFLFK) was submitted to EFSA to be risk assessed as full‐scope, i.e. for import, processing, and food and feed uses, within the EU. Oilseed rape LBFLFK was developed to alter its fatty acid profile and to confer tolerance to imidazolinone herbicides.

The rotation period distributions of 4--10 Myr T Tauri stars in Orion OB1: New constraints on pre-main-sequence angular momentum evolution

open access: yes, 2016
Most existing studies of the angular momentum evolution of young stellar populations have focused on the youngest (1-3 Myr) T Tauri stars. In contrast, the angular momentum distributions of older T Tauri stars (4-10 Myr) have been less studied, even ...

Accretion-related properties of Herbig Ae/Be stars. Comparison with T Tauris [PDF]

open access: yes, 2012
We look for trends relating the mass accretion rate (Macc) and the stellar ages (t), spectral energy distributions (SEDs), and disk masses (Mdisk) for a sample of 38 HAeBe stars, comparing them to analogous correlations found for classical T Tauri stars.

Gender and Segregation: An Introduction

open access: yesGender &History, Volume 37, Issue 3, Page 795-804, October 2025.
ABSTRACT This introduction to the Special Issue explores the ways in which a gendered analysis illuminates histories of segregation. It argues three key points. First, it is essential to understand segregation from an intersectional perspective, one that fully integrates gender alongside other factors and dynamics in order to fully understand the ...

Very Low Mass Stars and Brown Dwarfs in Taurus-Auriga

open access: yes, 2002
We present high resolution optical spectra obtained with the HIRES spectrograph on the Keck I telescope of low mass T Tauri stars and brown dwarfs (LMTTs) in Taurus-Auriga.

An ecological framework for microbial metabolites in the ocean ecosystem

open access: yesLimnology and Oceanography Letters, Volume 10, Issue 5, Page 636-659, September 2025.
Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,
