Neutron powder diffraction has been used to observe the changes in hydrogen bonding that occur as a function of temperature in ND4IO3, and thus determine the structural features that occur during the low temperature (103 K) phase transition. We sho... Read More about Investigation of the changes in hydrogen bonding accompanying the structural reorganization at 103K in Ammonium iodate.

Monthly Notices of the Royal Astronomical Society, 486(2), 2129-2136. https://doi.org/10.1093/mnras/stz875

We started a program to search for companions around hybrid δ Sct/γ Dor stars with the frequency modulation method using Kepler data. Our best candidate was KIC 5709664, where we could identify Fourier peaks with sidelobes, suggesting binary orbital...

The Gaia-ESO Survey: asymmetric expansion of the Lagoon Nebula cluster NGC 6530 from GES and Gaia DR2. Monthly Notices of the Royal Astronomical Society, 486(2), 2477-2493. https://doi.org/10.1093/mnras/stz870

The combination of precise radial velocities from multi-object spectroscopy and highly accurate proper motions from Gaia DR2 opens up the possibility for detailed 3D kinematic studies of young star-forming regions and clusters. Here, we perform such... Read More about The Gaia-ESO Survey: asymmetric expansion of the Lagoon Nebula cluster NGC 6530 from GES and Gaia DR2.

The Gaia-ESO Survey: Age spread in the star forming region NGC 6530 from the HR diagram and gravity indicators (2019)
Journal Article
Prisinzano, L., Damiani, F., Kalari, V., Jeffries, R., Bonito, R., Micela, G., …Zaggia, S. (2019). The Gaia-ESO Survey: Age spread in the star forming region NGC 6530 from the HR diagram and gravity indicators. Astronomy & Astrophysics, 623, Article A159. https://doi.org/10.1051/0004-6361/201834870

Context. In very young clusters, stellar age distribution is empirical proof of the duration of star cluster formation and thus it gives indications of the physical mechanisms involved in the star formation process. Determining the amount of interste... Read More about The Gaia-ESO Survey: Age spread in the star forming region NGC 6530 from the HR diagram and gravity indicators.

Substituent effects in the zinc(II) coordination chemistry of isomeric pyridylpyrazole ligands (2019)
Journal Article

Pyrazoles with unsymmetric substitution are useful ligands in coordination chemistry, but are under-developed due to synthetic challenges in accessing the pure isomers. We have prepared four new structurally related N-(2-pyridyl)-3,5-dialkylpyrazole... Read More about Substituent effects in the zinc(II) coordination chemistry of isomeric pyridylpyrazole ligands.
