A kinematic and structural study of young open clusters in the Milky Way Galaxy using Gaia DR3 catalogue
Harsha K. H., Annapurni Subramaniam, S. R. Dhanush +1
We aim to identify the cluster members, estimate cluster properties, study the dynamical state of the clusters as a function of mass, trace the existence of dynamical effects in ma…
Exploring membership and variability in NGC 7419: An open cluster rich in super giants and Be type stars
Arghya Chakraborty, Jessy Jose, Alex C. Carciofi
NGC 7419 is a young open cluster notable for hosting five Red Supergiants and a high abundance of Classical Be (CBe) stars. CBe stars are main sequence non-supergiant B-type stars,…
Search for Brown Dwarfs in IC 1396 with Subaru HSC: Interpreting the Impact of Environmental Factors on Sub-stellar Population
Saumya Gupta, Jessy Jose, Swagat Ranjan Das +4
Young stellar clusters are predominantly the hub of star formation and hence, ideal to perform comprehensive studies over the least explored sub-stellar regime. Various unanswered…
Multi-wavelength detection of an ongoing FUOr-type outburst on a low-mass YSO
Zhen Guo, P. W. Lucas, R. G. Kurtev +13
During the pre-main-sequence evolution, Young Stellar Objects (YSOs) assemble most of their mass during the episodic accretion process. The rarely seen FUOr-type events (FUOrs) are…
H emission line sources from VLT-MUSE in a low-metallicity star forming region -- Dolidze 25
Mizna Ashraf, Jessy Jose, Gregory Herczeg +1
The process of accretion through circumstellar disks in young stellar objects is an integral part of star formation and the emission line is a prominent signature of accretion…
A novel survey for young substellar objects with the W-band filter VI: Spectroscopic census of sub-stellar members and the IMF of Orionis cluster
Belinda Damian, Jessy Jose, Beth Biller +11
Low-mass stars and sub-stellar objects are essential in tracing the initial mass function (IMF). We study the nearby young Orionis cluster (d408 pc; age1.8 Myr) usi…
Photometric and Spectroscopic monitoring of YSOs in nearby star forming regions. I. Eruptive YSOs
Carlos Contreras Peña, Gregory J. Herczeg, Mizna Ashraf +7
Mid-infrared (mid-IR) variability in young stellar objects (YSOs) is driven by several physical mechanisms, which produce a variety of amplitudes and light curve shapes. One of the…
Survey of Hα emission-line stars in the star-forming region IC 5070
Neelam Panwar, Jessy Jose, Rishi C
Actively accreting young stellar objects show H emission line in their spectra. We present the results of survey for H emission-line stars in the star-forming region IC~5070…
A Novel Survey for Young Substellar Objects with the W band Filter.V. IC 348 and Barnard 5 in the Perseus Cloud
Bhavana Lalchand, Wen-Ping Chen, Beth A. Biller +10
We report the discovery of substellar objects in the young star cluster IC 348 and the neighboring Barnard 5 dark cloud, both at the eastern end of the Perseus star-forming complex…
Diagnosing FUor-like Sources: The Parameter Space of Viscously Heated Disks in the Optical and Near-IR
Hanpu Liu, Gregory J. Herczeg, Doug Johnstone +8
FU Ori type objects (FUors) are decades-long outbursts of accretion onto young stars that are strong enough to viscously heat disks so that the disk outshines the central star. We…
A Comprehensive Study of the Young Cluster IRAS 05100+3723: Properties, Surrounding Interstellar Matter, and Associated Star Formation
R. K. Yadav, M. R. Samal, E. Semenko +13
We present a comprehensive multiwavelength investigation of a likely massive young cluster `IRAS 05100+3723' and its environment with the aim to understand its formation history an…
A Novel Survey for Young Substellar Objects with the W-band filter III: Searching for very low mass brown dwarfs in Serpens South and Serpens Core
Sophie Dubber, Beth Biller, Katelyn Allers +10
We present CFHT photometry and IRTF spectroscopy of low-mass candidate members of Serpens South and Serpens Core (430 pc, 0.5 Myr), identified using a novel combination…
Early Warning Signals Indicate a Critical Transition in Betelgeuse
Sandip V. George, Sneha Kachhara, Ranjeev Misra +1
Critical transitions occur in complex dynamical systems, when the system dynamics undergoes a regime shift. These can often occur with little change in the mean amplitude of system…
A Novel Survey for Young Substellar Objects with the W-band filter II. The Coolest and Lowest Mass Members of the Serpens-South Star-forming Region
Jessy Jose, Beth A. Biller, Loıc Albert +13
Given its relative proximity (~430 pc), compact size (< 20'), young age (~ 0.5 Myr) and rich number of young stellar objects, the Serpens-South star forming region is a promising s…
Classification of Close Binary Stars Using Recurrence Networks
Sandip V. George, R. Misra, G. Ambika
Close binary stars are binary stars where the component stars are close enough such that they can exchange mass and/or energy. They are subdivided into semi-detached, overcontact o…
An initial overview of the extent and structure of recent star formation within the Serpens Molecular Cloud using Gaia Data Release 2
Gregory J. Herczeg, Michael A. Kuhn, Xingyu Zhou +7
The dense clusters within the Serpens Molecular Cloud are among the most active regions of nearby star formation. In this paper, we use Gaia DR2 parallaxes and proper motions to st…
Characterization of Stellar and Substellar Members in the Coma Berenices Star Cluster
Shih-Yun Tang, W. P. Chen, P. S. Chiang +3
We have identified stellar and substellar members in the nearby star cluster Coma Berenices, using photometry, proper motions, and distances of a combination of 2MASS, UKIDSS, URAT…
