We present stellar proper motions in the Galactic bulge from the Sagittarius Window Eclipsing Extrasolar Search (SWEEPS) project using ACS/WFC on HST. Proper motions are extracted for more than...
Planets in the Galactic Bulge: Results from the SWEEPS Project (2007)
Sahu, Kailash C., Casertano, Stefano, Valenti, Jeff, Bond, Howard E., Brown, Thomas M., Smith, T. Ed, ...
The exoplanets discovered so far have been mostly around relatively nearby and bright stars. As a result, the host stars are mostly (i) in the Galactic disk, (ii) relatively massive, and (iii)...

We have determined the projected rotational velocities of thirteen blue horizontalbranch (BHB) stars in the globular cluster M13 via rotational broadening of metal absorption lines. Our sample spans...
Altmann, Martin, Catelan, Marcio, Zoccali, Manuela
Kinematics combined with detailed element abundances provide the method of analysis of stellar populations using as much available information as possible, in contrast to other methods. Here we...
The Galactic Bulge: A Review (2007)
Minniti, Dante, Zoccali, Manuela
The Milky Way is the only galaxy for which we can resolve individual stars at all evolutionary phases, from the Galactic center to the outskirt. The last decade, thanks to the advent of near IR...
Hoyer, Sergio, Alegria, Sebastian Ramirez, Ivanov, Valentin D., Minniti, Dante, Pietrzynski, Grzegorz, Ruiz, Maria Teresa, ...
We present precise new V, I, and K-band photometry for the planetary transit candidate star OGLE-TR-82. Good seeing V-band images acquired with VIMOS instrument at ESO VLT allowed us to measure...
Variations in the lithium abundances of turn off stars in the globular cluster 47 Tuc (2007)
Bonifacio, Piercarlo, Pasquini, Luca, Molaro, Paolo, Carretta, Eugenio, François, Patrick, Gratton, Raffaele G., ...
aims: Our aim is to determine Li abundances in TO stars of the Globular Cluster 47 Tuc and test theories about Li variations among TO stars. method: We make use of high resolution (R~ 43000), high...
Díaz, Rodrigo F., Ramírez, Sebastián, Fernández, José Miguel, Gallardo, José, Gieren, Wolfgang, Ivanov, Valentin D., ...
We present precise V and Ks-band transit photometry for the planetary host star OGLE-TR-113. Using the Ks-band photometry, we confirm the dwarf nature of OGLE-TR-113, and obtain new estimates for its...
Minniti, Dante, Fernández, José Miguel, Díaz, Rodrigo F., Udalski, Andrzej, Pietrzynski, Grzegorz, Gieren, Wolfgang, ...
We present accurate V-band photometry for a planetary transit of OGLE-TR-111 acquired with VIMOS at the ESO Very Large Telescope. The measurement of this transit allows to refine the planetary...

Carraro, Giovanni, Moitinho, Andre', Zoccali, Manuela, Vazquez, Ruben, Baume, Gustavo
We perform a detailed photometric study of the stellar populations in a Galactic Field at l = 232, b = -6 in the Canis Major (CMa) constellation. We present the first U,B,V,I photometry of the old...
Transiting extrasolar planetary candidates in the Galactic bulge (2006)
Sahu, Kailash C., Casertano, Stefano, Bond, Howard E., Valenti, Jeff, Smith, T. Ed, Minniti, Dante, ...
More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and more recently...
Millimagnitude optical photometry for the transiting planetary candidate OGLE-TR-109 (2006)
Fernández, José Miguel, Minniti, Dante, Pietrzynski, Grzegorz, Gieren, Wolfgang, Ruiz, María Teresa, Zoccali, Manuela, ...
We present precise V-band photometry for the low-amplitude transit candidate star OGLE-TR-109. This is an extreme case among the transiting candidates found by the OGLE group because of the early...

Hot subdwarfs in the Galactic Bulge (2005)
Busso, Giorgia, Moehler, Sabine, Zoccali, Manuela, Heber, Uli
Recent observations and theories suggest that extreme horizontal branch (EHB) stars and their progeny should be the cause of the UV excess seen in the spectra of many elliptical galaxies. Since the...
