My query isn't changing $post in theme_loop/author.php

I wrote this code

<?php 

		$args = array("author" 		=> get_query_var('author'),
				"post_type" 	=> array("post","gallery"),
				"paged"		=> $paged,
				"posts_per_page"	=> 10,
				"orderby"	=> "date",
				"order"		=> "DESC");

		$myQuery = new WP_Query($args);

		?>
			<?php if ($myQuery->have_posts()) : while ($myQuery->have_posts()) : $myQuery->the_post(); ?>
				<?php get_template_part(THEME_LOOP."author"); ?>

but if i dump the variable $post in author php file it is the primary query result… someone can tell me where am i wrong?
Thank you
