The lifetime of protoplanetary disks is a crucial parameter for planet formation research.
Observations of disk fractions in star clusters imply median disk lifetimes of 1–3 Myr. This …

ABSTRACT The second Gaia Data Release (DR2) contains astrometric and photometric
data for more than 1.6 billion objects with mean Gaia G magnitude< 20.7, including many …

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 …

In the star-formation process, the vital impact of environmental factors such as feedback from
massive stars and stellar density on the form of the initial mass function (IMF) at the low …

Context. Through observations numerous giant molecular filaments (GMFs) have been
discovered in the Milky Way. Their role in the Galactic star formation and Galaxy-scale …

ABSTRACT A naive Bayes classifier for identifying Class II YSOs has been constructed and
applied to a region of the Northern Galactic Plane containing 8 million sources with good …

The role of metallicity in sha** protoplanetary disk evolution remains poorly
comprehended. This study analyzes the disk fraction of 10 young (0.9–2.1 Myr) and low …

We have performed a detailed analysis of the Czernik 3 (Cz3) open cluster by using deep
near-infrared photometry taken with TIRCAM2 on the 3.6 m Devasthal optical telescope …

Identifying and characterizing young populations of star-forming regions are crucial to
unraveling their properties. In this regard, Gaia-DR3 data and machine-learning tools are …

Using our deep optical and near-infrared photometry along with multiwavelength archival
data, we here present a detailed study of the Galactic H ii region Sh 2-305 to understand the …
