Abstract

With the third data release of the Gaia mission $Gaia$ DR3 with its precise photometry and astrometry, it is now possible to study the behaviour of stars at a scale never seen before. In this paper, we developed new criteria to identify T-Tauri stars (TTS) candidates using UV and optical CMDs by combining the GALEX and Gaia surveys. We found 19 TTS candidates and 5 of them are newly identified TTS in the Taurus Molecular Cloud (TMC), not catalogued before as TMC members. For some of the TTS candidates, we also obtained optical spectra from several Indian telescopes. We also present the analysis of the distance and proper motion of young stars in the Taurus using data from $Gaia$ DR3. We found that the stars in Taurus show a bimodal distribution with distance, having peaks at $130.17_{-1.24}^{1.31}$ pc and $156.25_{-5.00}^{1.86}$ pc. The reason for this bimodality, we think, is due to the fact that different clouds in the TMC region are at different distances. We further show that the two populations have similar ages and proper motion distribution. Using the $Gaia$ DR3 colour-magnitude diagram, we show that the age of Taurus is consistent with 1 Myr., Comment: 13 pages, 10 figures

47. Teacher Well-Being and Intentions to Leave: Finding from the 2023 State of the American Teacher Survey. American Educator Panels. Research Report. RR-A1108-8

Abstract

The well-being and mental health of kindergarten through grade 12 (K-12) public school teachers has been a topic of national concern during the coronavirus disease 2019 (COVID-19) pandemic. In 2021 and 2022, teachers were twice as likely to report experiencing frequent job-related stress and difficulty coping with their job-related stress than the general population of working adults. Restoring teacher well-being could improve job performance and job satisfaction and boost retention for teachers of all backgrounds. Recent media reports suggest that many districts and schools across the country are implementing new programs -- or expanding existing offerings -- intended to reduce teacher stress and burnout and promote well-being and retention. This report presents selected findings from the 2023 State of the American Teacher survey related to teacher well-being, the availability of mental health and well-being supports, and teachers' intentions to leave their current teaching jobs. The findings in this report are descriptive and intended to inform federal, state, and local education leaders and policymakers about the state of the teacher workforce.
