The Gaia Ultracool Dwarf Sample -- IV. GTC/OSIRIS optical spectra of Gaia late-M and L dwarfs
W. J. Cooper, H. R. A. Jones, R. L. Smart +20
As part of our comprehensive, ongoing characterisation of the low-mass end of the main sequence in the Solar neighbourhood, we used the OSIRIS instrument at the 10.4 m Gran Telesco…
Peering into the Heart of the Giant Molecular Cloud G148.24+00.41: A Deep Near-infrared View of the Newly Hatched Cluster FSR 655
Vineet Rawat, M. R. Samal, D. K. Ojha +5
We present a detailed near-infrared study of an embedded cluster located in the hub of the giant molecular cloud G148.24+00.41 of mass 10 , with the TANSPEC inst…
Linear polarization study of open clusters towards the anticenter direction: Signature of the spiral arms
Namita Uppal, Shashikiran Ganesh, Vincent Pelgrims +2
Our objective is to investigate the distribution of dust and associated large-scale structures of the Galaxy using optical linear polarization measurements of various open clusters…
On the Response of the Transition Region and the Corona to Rapid Excursions in the Chromosphere
Ravi Chaurasiya, Ankala Raja Bayanna, R. E. Louis +2
Spicules are the thin hair/grass-like structures that are prominently observed at the chromospheric solar limb. It is believed that fibrils and rapid blueshifted and redshifted exc…
Study of Wolf-Rayet stars using uGMRT
Anindya Saha, Anandmayee Tej, Santiago del Palacio +4
In recent years, systems involving massive stars with large wind kinetic power have been considered as promising sites for investigating relativistic particle acceleration in low r…
A dusty rain falls on the nova V959 Monocerotis
A. Evans, D. P. K. Banerjee, W. P. Varricatt +1
We present archival and ground-based infrared observations of the gamma-ray-emitting nova V959 Mon, covering the period 100-4205 days after the 2012 eruption. We use these data to…
