Exploring the optical properties of redback pulsars: The case of J1717+4308A in the globular cluster M92
Jianxing Chen, Greta Ettorre, Cristina Pallanca +13
Binary millisecond pulsars (MSPs) in globular clusters (GCs) are key for binary and stellar evolution studies under extreme conditions. The identification of their optical companio…
CRIRES+ reveals the chemistry of the stellar sub-populations in the bulge fossil fragment Liller 1
L. Chiappino, L. Origlia, C. Fanelli +10
In this paper we present the chemical screening of the complex stellar population discovered in the Bulge Fossil Fragment Liller 1. This study is part of the Bulge Cluster Origin (…
The one and the only: the pulsar - white dwarf system in NGC 6749
Paulo C. C. Freire, Yinfeng Dai, Mario Cadelano +7
PSR J1905+0154A is a binary millisecond pulsar located in the globular cluster (GC) NGC 6749. It was discovered in 2004 in a search for pulsars in GCs carried out with the Arecibo…
The Bulge Cluster Origin (BulCO) survey with CRIRES at the ESO-VLT: a chemical screening of the Globular Cluster NGC 6553
A. Bartolomei, L. Origlia, C. Fanelli +10
In this paper we present the chemical screening of the stellar population belonging to the globular cluster NGC 6553 in the Galactic bulge. This study has been conducted in the con…
Revealing the stellar population of the ultra-obscured Galactic globular cluster Glimpse-C02
M. Loriga, M. Cadelano, C. Pallanca +10
In this paper, we present the results of a detailed photometric analysis of Glimpse-C02, one of the most extincted globular clusters of the Milky Way. We built a deep color magnitu…
A binary-related origin mediated by environmental conditions for blue straggler stars
Francesco R. Ferraro, Barbara Lanzoni, Enrico Vesperini +7
Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enh…
