Astronomy & Astrophysics, 2005 Using the UVES echelle spectrograph at the ESO VLT we obtained two-dimensional high-resolution (R = 50 000) spectra of the edge-on disk objects HH30*, HK Tau B, and HV Tau C. For comparison purposes we also observed with the same equipment both the classical T Tauri star HL Tau and the active late-type star LDN 1551-9. The spectra of all three observed

ON THE SPECTRAL AND PHOTOMETRIC ACTIVITY IN YOUNG STARS
Odessa Astronomical Publications, 2017 Results of long time homogenous medium resolution spectral observations of classic T Tauri type stars DI Cep, T Tau and GW Ori obtained during 1972-1990 are analyzed.

A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission
The Astrophysical Journal Supplement Series, 2022 Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%–50%, likely induced by occultations due to circumstellar disk material.

The IC2118 association: new T Tauri stars in high-latitude molecular clouds
, 2004 We identified new pre-main sequence stars in the region of high-latitude molecular clouds associated with the reflection nebula IC2118, around l = 208 degr and b = -27 degr. The stars were selected as T Tauri candidates in objective prism plates obtained

Discovery of "isolated" comoving T Tauri stars in Cepheus [PDF]
, 2010 During the course of a large spectroscopic survey of X-ray active late-type stars in the solar neighbourhood, we discovered four lithium-rich stars packed within just a few degrees on the sky.

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.

A Comprehensive Analysis of Rovibrational CO in the Era of JWST
The Astronomical JournalWe 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.

Tests of Disk-locking in T Tauri Stars of the Orion Nebula Cluster
The Astrophysical JournalWe look for specific correlations predicted by magnetospheric accretion models for young stars that assume disk-locking using stellar and accretion parameters derived from low-resolution HST-STIS spectra of 33 T Tauri stars in the Orion Nebula Cluster ...

Gendering Late Ottoman Society and Reconstructing Gender in the Women's Press
Gender &History, EarlyView.ABSTRACT This article analyses the construction of gender differences in the late Ottoman Empire through women's periodicals, which acted as a key medium in the redefinition of gender roles. It examines how new understandings of gender roles emerged amid rapid transformations in traditional societal structures, particularly in the women’s press.
