Molecular Ecology, Volume 35, Issue 2, January 2026.ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Dynamo processes in the T Tauri star V410 Tau [PDF]
, 2009 We present new brightness and magnetic images of the weak-line T Tauri star V410 Tau, made by using data from the Narval spectropolarimeter at T´ elescope Bernard Lyot (TBL).

Measuring the Magnetic Field of the Classical T Tauri Star TW Hydrae [PDF]
, 2005 We present infrared (IR) and optical echelle spectra of the classical T Tauri star TW Hydrae. Using the optical data, we perform detailed spectrum synthesis to fit atomic and molecular absorption lines and determine key stellar parameters: Teff = 4126 ...

, 2009 We report on observation and determination of rotational periods of ten weak-line T Tauri stars in the Cepheus-Cassiopeia star-forming region. Observations were carried out with the Cassegrain-Teleskop-Kamera (CTK) at University Observatory Jena between ...

Ethical mediation: Navigating research ethics and frictions in overseas fieldwork
Area, Volume 57, Issue 4, December 2025.Short Abstract This paper problematises the application of UK‐based research ethics policy for overseas fieldwork. It draws on the fieldwork experiences of two researchers affiliated with UK universities and conducting fieldwork overseas in their home country.

A WIDELY SEPARATED, HIGHLY OCCLUDED COMPANION TO THE NEARBY LOW-MASS T TAURI STAR TWA 30 [PDF]
, 2010 We report the discovery of TWA 30B, a wide (∼3400 AU), co-moving M dwarf companion to the nearby (∼42 pc) young star TWA 30. Companionship is confirmed from their statistically consistent proper motions and radial velocities (RVs), as well as a chance ...

Dispersed T Tauri stars and galactic star formation
AIP Conference Proceedings, 1996 The spatial distribution, age distribution and kinematics of T Tauri stars, both close to and widely distributed around active clouds, are considered using simple models of T Tauri dispersal. Models are compared to observations in and around the nearby cloud complexes, in particular the recent discovery of widely scattered young stars from the ROSAT ...

JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk
The Astrophysical JournalWe present MIRI Medium-resolution Spectrograph observations of the large, multi-gapped protoplanetary disk around the T Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9–25.5 μ m toward the inner ∼1 au in the disk ...
