Thorne–Żytkow objects (TŻOs) are a class of stellar object comprised of a neutron star core surrounded by a large and diffuse envelope. Their exterior appearance is identical to red supergiants; the distinctive electromagnetic signature of a TŻO is a suite of unusual chemical abundance patterns, including excesses of Li, Rb, Mo, and Ca. However, electromagnetic observations cannot unambiguously identify the presence of a neutron star core. Detection of continuous gravitational wave emission… 
Status and Perspectives of Continuous Gravitational Wave Searches
The birth of gravitational wave astronomy was triggered by the first detection of a signal produced by the merger of two compact objects (also known as a compact binary coalescence event). The

Optimizing the Third Generation of Gravitational-wave Observatories for Galactic Astrophysics
Gravitational-wave (GW) astrophysics is a rapidly expanding field, with plans to enhance the global ground-based observatory network through the addition of larger, more sensitive observatories: the
Properties of Thorne–Żytkow object explosions
Thorne–Żytkow objects are stars that have a neutron star core with an extended hydrogen-rich envelope. Massive Thorne–Żytkow objects are proposed to explode when the nuclear reactions sustaining


HV2112, a Thorne-Zytkow object or a super asymptotic giant branch star
The very bright red star HV2112 in the Small Magellanic Cloud could be a massive Thorne-A >> ytkow object (TA >> O), a supergiant-like star with a degenerate neutron core. With a luminosity of over
The M Supergiant High-mass X-Ray Binary 4U 1954+31
The X-ray binary 4U 1954+31 has been classified as a low-mass X-ray binary containing an M giant and a neutron star (NS). It has also been included in the rare class of X-ray symbiotic binaries. The
The main sequence of three red supergiant clusters
Massive clusters in our Galaxy are an ideal testbed to investigate the properties and evolution of high-mass stars. They provide statistically significant samples of massive stars of uniform ages. To
A third cluster of red supergiants in the vicinity of the massive cluster RSGC3
This research is partially supported by the Spanish Ministerio de Ciencia e Innovacion (MCINN) under AYA2010-21697-C05-5 and the Consolider-Ingenio 2010 programme grant CSD2006-00070: First Science
A massive association around the obscured open cluster RSGC3
Context. Four clusters of red supergiants have been discovered in a region of the Milky Way close to base of the Scutum-Crux Arm and the tip of the Long Bar. Population synthesis models indicate that
Another cluster of red supergiants close to RSGC1
Context. Recent studies have revealed massive star clusters in a region of the Milky Way close to the tip of the Long Bar. These clusters are heavily obscured and are characterised by a population of
Searching for gravitational waves from Cassiopeia A with LIGO
We describe a search underway for periodic gravitational waves from the central compact object in the supernova remnant Cassiopeia A. The object is the youngest likely neutron star in the Galaxy. Its
The Cool Supergiant Population of the Massive Young Star Cluster RSGC1
We present new high-resolution near-IR spectroscopy and OH maser observations to investigate the population of cool luminous stars of the young massive Galactic cluster RSGC1. Using the 2.293 μm CO
A Massive Cluster of Red Supergiants at the Base of the Scutum-Crux Arm
We report on the unprecedented red supergiant (RSG) population of a massive young cluster, located at the base of the Scutum-Crux Galactic arm. We identify candidate cluster RSGs based on 2MASS
