TL;DR
This survey utilizes AKARI mid-infrared data combined with other catalogs to identify new T Tauri star candidates in the Taurus-Auriga region, proposing criteria to distinguish them from similar objects.
Contribution
The paper introduces new selection criteria for T Tauri stars using AKARI MIR data and demonstrates their effectiveness in identifying candidates in a large sky area.
Findings
Identified 28 new T Tauri star candidates.
Achieved a ~75% probability of correct TTS identification.
Demonstrated the potential for all-sky TTS searches using MIR data.
Abstract
Aims: We search new T Tauri star (TTS) candidates with the mid-infrared (MIR) part of the AKARI All-Sky Survey at 9 and 18 um wavelengths. Methods: We used the point source catalogue (PSC), obtained by the Infrared Camera (IRC) on board AKARI. We combined the 2MASS PSC and the 3rd version of the USNO CCD Astrograph Catalogue (UCAC) with the AKARI IRC-PSC, and surveyed 517 known TTSs over a 1800-square-degree part of the Taurus-Auriga region to find criteria to extract TTSs. We considered asymptotic giant branch (AGB) stars, post-AGB stars, Planetary Nebulae (PNe), and galaxies, which have similar MIR colours, to separate TTSs from these sources. Results: Of the 517 known TTSs, we detected 133 sources with AKARI. Based on the colour-colour and colour-magnitude diagrams made from the AKARI, 2MASS, and UCAC surveys, we propose the criteria to extract TTS candidates from the AKARI All-Sky…
