Discovery of 118 New Ultracool Dwarf Candidates Using Machine Learning Techniques
Hunter Brooks, Dan Caselden, J. Davy Kirkpatrick +44
We present the discovery of 118 new ultracool dwarf candidates, discovered using a new machine learning tool, named \texttt{SMDET}, applied to time series images from the Wide-fiel…
Measuring the Spot Variability of T Tauri Stars Using Near-IR Atomic Fe and Molecular OH Lines
Shih-Yun Tang, Christopher M. Johns-Krull, L. Prato +1
As part of the Young Exoplanets Spectroscopic Survey (YESS), this study explores the spot variability of 13 T Tauri Stars (TTSs) in the near-infrared band, using spectra from t…
The Present-Day Mass Function of Star Clusters in the Solar Neighborhood
Xiaoying Pang, Siqi Liao, Jiadong Li +5
This work analyses the present-day mass function (PDMF) of 93~star clusters utilizing Gaia DR3 data, with membership determined by the StarGo machine learning algorithm. The impact…
Binary Star Evolution in Different Environments: Filamentary, Fractal, Halo and Tidal-tail Clusters
Xiaoying Pang, Yifan Wang, Shih-Yun Tang +7
Using membership of 85 open clusters from previous studies (Pang et al. 2021a,b, 2022b; Li et al. 2021) based on Gaia DR3 data, we identify binary candidates in the color-magnitude…
Star-Crossed Lovers DI Tau A and B: Orbit Characterization and Physical Properties Determination
Shih-Yun Tang, Asa G. Stahl, L. Prato +5
The stellar companion to the weak-line T Tauri star DI Tau A was first discovered by the lunar occultation technique in 1989 and was subsequently confirmed by a speckle imaging obs…
Dynamical Origin for the Collinder 132-Gulliver 21 Stream: A Mixture of three Co-Moving Populations with an Age Difference of 250 Myr
Xiaoying Pang, Yuqian Li, Shih-Yun Tang +6
We use Gaia DR3 data to study the Collinder 132-Gulliver 21 region via the machine learning algorithm StarGO, and find eight subgroups of stars (ASCC 32, Collinder 132 gp 1--6, Gul…
3D Morphology of Open Clusters in the Solar Neighborhood with Gaia EDR3 II: Hierarchical Star Formation Revealed by Spatial and Kinematic Substructures
Xiaoying Pang, Shih-Yun Tang, Yuqian Li +9
We identify members of 65 open clusters in the solar neighborhood using the machine-learning algorithm StarGO based on Gaia EDR3 data. After adding members of twenty clusters from…
TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux
Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt +48
Mature super-Earths and sub-Neptunes are predicted to be Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15 planets around young stars even if t…
Evidence of Early-stage Tidal Structures of Open Clusters Revealed by Kinematics with Gaia EDR3
Yezhang Li, Xiaoying Pang, Shih-Yun Tang
Blanco 1, a 100Myr open cluster in the solar neighborhood, is well known for its two 50pc-long tidal tails. Taking Blanco 1 as a reference, we find evidence of early-stage tidal di…
The JCMT Transient Survey: Four Year Summary of Monitoring the Submillimeter Variability of Protostars
Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee +49
We present the four-year survey results of monthly submillimeter monitoring of eight nearby (pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargl…
Disruption of Hierarchical Clustering in the Vela OB2 Complex and the Cluster Pair Collinder 135 and UBC7 with Gaia EDR3: Evidence of Supernova Quenching
Xiaoying Pang, Zeqiu Yu, Shih-Yun Tang +4
We identify hierarchical structures in the Vela OB2 complex and the cluster pair Collinder 135 and UBC 7 with Gaia EDR3 using the neural network machine learning algorithm StarGO.…
Impacts of Water Latent Heat on the Thermal Structure of Ultra-Cool Objects: Brown Dwarfs and Free-Floating Planets
