CSI 2264: Accretion process in classical T Tauri stars in the young cluster NGC 2264 [PDF]
, 2015 Our goal is to relate the photometric and spectroscopic variability of classical T Tauri stars, of the star-forming cluster NGC 2264, to the physical processes acting in the stellar and circumstellar environment, within a few stellar radii from the star.

X-Ray Observation on the Monoceros R2 Star-Forming Region with the Chandra ACIS-I Array
, 2003 We report on the results of the Chandra observation on the central region of the Monoceros R2 cloud (Mon R2), a high-mass star-forming region (SFR). With a deep exposure of 100 ks, we detected 368 X-ray sources, 80% of which were identified with the NIR ...

Food and Energy Security, Volume 14, Issue 3, May/June 2025.ABSTRACT Iron deficiency anemia (IDA) is alarmingly prevalent in sub‐Saharan Africa, where populations often rely on nutrient‐poor staple crops as their primary energy source. The East African highland banana (EAHB), a staple for millions in Uganda and most of East Africa's highlands, contains insufficient iron to meet dietary needs.

New Phytologist, Volume 246, Issue 4, Page 1724-1739, May 2025.Summary Phasing biological and physiological processes to periodic light–dark cycles is crucial for the life of most organisms. Marine diatoms, as many phytoplanktonic species, exhibit biological rhythms, yet their molecular timekeepers remain largely uncharacterized.

The enviroments of T Tauri stars
The Astrophysical Journal, 1983 The environments of T Tauri stars are probably determined by the interaction of a stellar wind with matter which is falling toward a newly formed star. As shown by Ulrich, the steady infall of cool gas with angular momentum toward the star leads to a density distribution with rhoproportionalr/sup -1/2/ inside a radius r/sub d/ and rhoproportionalr/sup -

The Political Quarterly, Volume 96, Issue 2, Page 340-355, April/June 2025.Abstract Within the extensive literature on the powers and constraints of British prime ministers, there has been little comparison of the extent to which the premiers themselves have perceived or projected a personal entitlement to determine government policy.

Some resolutions on T Tauri stars [PDF]
Symposium - International Astronomical Union, 1990 This symposium is dedicated to the results of studies of flare stars. The necessity of the detailed analysis of observational data on flare stars follows from the very simple fact, that until now the theory has not found for the answer to the question: why the young stars of low luminosity are flaring.

Observations and Modeling of the Inner Disk Region of T Tauri Stars [PDF]
, 2004 We present observations of four T Tauri stars using long baseline infrared interferometry from the Palomar Testbed Interferometer. The target sources, T Tau N, SU Aur, RY Tau, and DR Tau, are all known to be surrounded by dusty circumstellar disks.

Dynamical investigations of the multiple stars
Open Astronomy, 2017 Two multiple stars - the quadruple star - Bootis (ADS 9173) and the triple star T Taury were investigated. The visual double star - Bootiswas studied on the basis of the Pulkovo 26-inch refractor observations 1982-2013.
