Uncovering a 260 pc wide, 35 Myr old filamentary relic of star formation
Giacomo Beccari, Henri M. J. Boffin, Tereza Jerabkova
Several recent studies have shown that the Vela OB2 region hosts a complex constellation of sub-populations with ages in the range 10 to 50 Myr. Such populations might represent th…
My companion is bigger than your companion!
Henri M. J. Boffin, Virginia Trimble
We provide an analysis of the mass ratio distribution as gathered from almost all of the 559 orbital solutions derived by Professor Roger Griffin in his long series in the Observat…
A stellar relic filament in the Orion star forming region
Tereza Jerabkova, Henri M. J. Boffin, Giacomo Beccari +1
We report the discovery of the oldest stellar substructure in the Orion star forming region (OSFR), the Orion relic filament. The relic filament is physically associated with the O…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
High-resolution transmission spectroscopy of four hot inflated gas giant exoplanets
Jiri Zak, Petr Kabath, Henri M. J. Boffin +2
The technique of transmission spectroscopy allows us to constrain the chemical composition of the atmospheres of transiting exoplanets. It relies on very high signal-to-noise spect…
When the tale comes true: multiple populations and wide binaries in the Orion Nebula Cluster
Tereza Jerabkova, Giacomo Beccari, Henri M. J. Boffin +5
The high-quality OmegaCAM photometry of the 3x3 deg around the Orion Nebula Cluster (ONC) in r, and i filters by Beccari et al.(2017) revealed three well-separated pre-main sequenc…
Barium & related stars and their white-dwarf companions I. Giant stars
A. Jorissen, H. M. J. Boffin, D. Karinkuzhi +4
This paper provides long-period and revised orbits for barium and S stars adding to previously published ones. The sample of barium stars with strong anomalies comprise all such st…
Detection limits of exoplanetary atmospheres with 2-m class telescopes
P. Kabath, J. Zak, H. M. J. Boffin +3
Transmission spectroscopy is an important technique to probe the atmospheres of exoplanets. With the advent of TESS and, in the future, of PLATO, more and more transiting planets a…
Latest advances in the abundance discrepancy problem in photoionized nebulae
J. García-Rojas, R. Wesson, H. M. J. Boffin +4
In this paper, we will focus on the advances made in the last few years regarding the abundance discrepancy problem in ionized nebulae. We will show the importance of collecting de…
Barium & related stars and their white-dwarf companions II. Main-sequence and subgiant stars
A. Escorza, D. Karinkuzhi, A. Jorissen +12
Barium (Ba) dwarfs and CH subgiants are the less-evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by a binary companion…
Spectral analysis of the barium central star of the planetary nebula Hen 2-39
L. Löbling, H. M. J. Boffin, D. Jones
Barium stars are peculiar red giants characterized by an overabundance of s-process elements along with an enrichment in carbon. These stars are discovered in binaries with white d…
Resolved imaging of the AR Puppis circumbinary disk
S. Ertel, D. Kamath, M. Hillen +14
Circumbinary disks are common around post-asymptotic giant branch (post-AGB) stars with a stellar companion on orbital time scales of a few 100 to few 1000 days. The presence of a…
