Polarimetric Approach Towards Membership Probability of Open Star Cluster NGC 2345
Sadhana Singh, Jeewan C. Pandey, Vishal Joshi
Using the linear polarimetric observations, we present a method to derive the membership probability of stars in cluster NGC 2345. The polarimetric observations of cluster NGC 2345…
Snowflakes in a furnace: formation of CO and dust in a recurrent nova eruption
D. P. K. Banerjee, C. E. Woodward, V. Joshi +7
We report the detection of carbon monoxide (CO) and dust, formed under hostile conditions, in recurrent nova V745 Sco about 8.7 days after its 2014 outburst. The formation of molec…
Optical and near-infrared spectroscopy of Nova V2891 Cygni: evidence for shock-induced dust formation
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +6
We present multi-epoch optical and near-infrared observations of the highly reddened, \pion{Fe}{ii} class slow nova V2891 Cygni. The observations span 15 months since its discovery…
V838 Monocerotis as seen by ALMA: a remnant of a binary merger in a triple system
Tomek Kamiński, Romuald Tylenda, Aleksandra Kiljan +6
V838 Mon erupted in 2002 quickly becoming the prototype of a new type of stellar eruptions known today as (luminous) red novae. The red nova outbursts are thought to be caused by s…
Interplanetary magnetic flux rope observed at ground level by HAWC
S. Akiyama, R. Alfaro, C. Alvarez +59
We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…
UV spectroscopy confirms SU Lyn to be a symbiotic star
Vipin Kumar, Mudit K. Srivastava, Dipankar P. K. Banerjee +1
SU Lyn, a star that ostensibly appears to be an unremarkable late M type giant, has recently been proposed to be a symbiotic star largely based on its hard X-ray properties. The st…
