Geodesics dynamics in the Linet-Tian spacetime with Lambda>0

Irene Brito, M. F. A. Da Silva, Filipe C. Mena +1

We analyse the geodesics' dynamics in cylindrically symmetric vacuum spacetimes with Lambda>0 and compare it to the Lambda=0 and Lambda<0 cases. When Lambda>0 there are two singula…

Period spacings in red giants; III. Coupling factors of mixed modes

B. Mosser, C. Pinçon, K. Belkacem +2

The power of asteroseismology relies on the capability of global oscillations to infer the stellar structure. For evolved stars, we benefit from unique information directly carried…

Stellar and planetary Cassini states

Alexandre C. M. Correia

Cassini states correspond to equilibria of the spin axis of a body when its orbit is perturbed. They were initially described for satellites, but the spin axis of stars and planets…

First scattered-light images of the gas-rich debris disk around 49 Ceti

É. Choquet, J. Milli, Z. Wahhaj +31

We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…

A quick start guide to BOND: Bayesian Oxygen and Nitrogen abundance Determinations in H II regions using strong and semistrong lines

N. Vale Asari, G. Stasińska, C. Morisset +1

We present a quick-start guide to BOND, a statistical method to derive oxygen and nitrogen abundances in H II regions. BOND compares a set of carefully selected strong and semistro…

Optical Depth Estimates and Effective Critical Densities of Dense Gas Tracers in the Inner Parts of Nearby Galaxy Discs

M. J. Jimenez-Donaire, F. Bigiel, A. K. Leroy +17

High critical density molecular lines like HCN(1-0) or HCO+(1-0) represent our best tool to study currently star-forming, dense molecular gas at extragalactic distances. The optica…
