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 ...

Exiles and innovators: a survey of heretics in sixteenth‐century Europe
Renaissance Studies, Volume 39, Issue 1, Page 26-40, February 2025.Abstract The links between exile and innovation have often been studied in the case of the twentieth century, but much less in the case of early modern Europe – an age of some political exiles and many religious ones. This essay focuses on what has been called ‘the Reformation of the Refugees’ in the early sixteenth century.

The Astrophysical JournalThe classical T Tauri star (CTTS) stage is a critical phase of the star and planet formation process. In an effort to better understand the mass accretion processes, which can dictate future stellar evolution and planet formation, a multiepoch ...

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 Plant Journal, Volume 121, Issue 2, January 2025.SUMMARY Plant genetic transformation is essential for understanding gene functions and developing improved crop varieties. Traditional methods, often genotype‐dependent, are limited by plants' recalcitrance to gene delivery and low regeneration capacity.

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.

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days
The Astrophysical JournalWe have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.

T Tauri and FU Orionis Stars [PDF]
Symposium - International Astronomical Union, 1975 A great deal of information on the continuous radiation of T Tau- and similar type stars has been acquired. The cause of the ultraviolet and infrared excess emission is discussed. The possibility that the blue continuum may arise from numerous line emissions is considered.

Ionization and heating by X-rays and cosmic rays*
EPJ Web of Conferences, 2015 High-energy radiation from the central T Tauri and protostars plays an important role in shaping protoplanetary disks and influences their evolution. Such radiation, in particular X-rays and extreme-ultraviolet (EUV) radiation, is predominantly generated
